The Smart Roadster 452 earns consistent praise from long-term owners for its mid-engine handling, kart-like agility and unique character. Common criticisms centre on water ingress, the Softouch gearbox’s learning curve and parts availability. Two decades on, most owners say they would buy one again.
When the Smart Roadster launched in 2003, magazine road tests focused on its quirky charm and sub-£10,000 entry price. Those reviews are now two decades old. The more meaningful verdict comes from the roughly 43,000 owners worldwide — around 7,251 of them in the UK — who have actually lived with these cars through cold winters, motorway commutes and weekend blasts. This article gathers the collective wisdom of that community: what has held up, what has caused headaches, and why so many owners refuse to sell. If you are thinking of buying one, or simply curious whether the reality matches the promise, this is the smart roadster review you needed.

What the Smart Roadster Review Community Agrees On: The Driving Experience
Ask any long-term owner what they love most and the answer is almost always the same: the way it drives. The 698cc three-cylinder turbo engine sits behind the seats in a true mid-rear configuration, giving a weight distribution that no front-engine sports car at this price point could match. The result is a car that rotates eagerly, changes direction with genuine precision, and communicates through the steering in a way that most modern sports cars — costing many times more — simply do not.
Owners consistently describe country-road pace as the car’s natural habitat. At 60 mph through a sequence of bends, the Roadster feels alive in a way that is disproportionate to its modest power output. The 60kW standard variant is widely regarded as the sweet spot: enough performance to be genuinely entertaining, with an oil cooler that the underpowered 45kW Lite model omits. If you want to understand how the variants stack up against one another, our detailed comparison of the 45kW, 60kW and Brabus 74kW models explains the real-world differences in performance and reliability.
Refinement is not the Roadster’s strongest suit, and experienced owners are honest about this. Wind noise from the soft top increases noticeably above 70 mph, and the three-cylinder engine is audible at all times. But for most owners, these are features rather than faults — part of the visceral, analogue experience that modern sports cars have largely designed away.
The Softouch Gearbox: The Marmite Element in Every Smart Roadster Review
No honest smart roadster review can sidestep the Softouch gearbox, and owner opinion is more divided on this component than any other. The system is an automated manual — it uses a conventional clutch and gear set, but the engagement is managed electronically rather than by a traditional clutch pedal. In theory it offers the best of both worlds. In practice, particularly in urban traffic, it demands patience and understanding that not every owner is willing to give it.
New owners frequently report frustration in the first weeks. Creeping in traffic, juddering on hill starts, and the characteristic pause between gear changes all catch people off guard if they expect conventional automatic behaviour. Those who persist, learn the gearbox’s logic and adapt their driving style typically become advocates. Those who expect it to behave like a torque-converter automatic often sell the car within a year. Our guide on how the Softouch system actually works is essential reading before you pass judgement — or before you buy.
The clutch itself is a wear item that owners monitor closely. High-mileage cars with town-heavy histories frequently need clutch attention, and the uprated 250 Nm unit has become the upgrade of choice for owners who want greater longevity and a more positive engagement feel.

Known Problems: What Two Decades of Ownership Has Revealed
The smart roadster owner review community is admirably honest about the car’s weaknesses, which is one reason the online forums remain so valuable. Water ingress is the single most discussed issue. The soft top, particularly on earlier cars, is prone to leaking at the rear quarters and around the hood catches. Left unaddressed, pooling water finds its way into the footwells, the SAM (Signal Acquisition Module) unit under the passenger seat, and the boot area. SAM faults — identifiable by B1xxx diagnostic codes — are almost always traceable to a damp environment rather than an inherently faulty component.
The steering rack draws regular mentions on owner forums, particularly on higher-mileage examples. Clonking or play in the steering is not unusual beyond 60,000 miles, and replacement racks — while not cheap — are a known and manageable cost. The LCD instrument cluster is another age-related concern: segments can fade or disappear, and replacement units are now primarily sourced from breakers or specialist suppliers.
Mechanically, the engine itself has a strong reputation for durability when serviced correctly. The turbocharger — a Garrett 1238S with a pneumatic wastegate — is generally robust, provided oil changes are performed on schedule and the engine is allowed to cool before shutdown after hard use. Owners who neglect oil changes on turbocharged engines pay for it universally; those who treat the Roadster conscientiously often report very high mileages without major engine work.
How the Smart Roadster Has Aged: Styling, Practicality and Daily Use
Twenty years after launch, the Roadster’s styling remains genuinely distinctive. It has not aged in the way that many contemporary sports cars have: there is no awkward mid-2000s aggression to it, just a clean, low-slung shape with proportions that still turn heads. The Roadster-Coupé body style, with its panoramic glass roof and additional boot volume, is considered by many owners to be the more practical daily choice — if you can find a good one.
Practicality in the conventional sense was never the point. The boot is in the front compartment — the engine is mid-rear, so there is no traditional engine bay at the nose — and it accommodates a weekend bag and little else. Cabin storage is minimal. For owners who understand this going in, it is never a problem; the car does one thing brilliantly and makes no apology for the rest. Our article exploring what using a Roadster as a daily driver is genuinely like covers the compromises in detail and is one of the most-read pieces on this site.
Values have risen meaningfully over the past five years as the surviving pool contracts and the car gains recognition as a modern classic. Clean, low-mileage examples now command prices that would have seemed absurd in 2015. Owners who held on through the depreciation trough have been vindicated.
The Brabus Variants: Are They Worth Seeking Out?
The Brabus name adds cachet, and both the 66kW SB2 and the full 74kW Brabus deliver meaningfully more performance through higher boost pressure — 1.43 bar in the case of the full Brabus versus 1.09 bar for the standard 60kW car. Owner consensus is broadly positive, though with caveats. Brabus cars were driven harder during their working lives, service histories are sometimes patchy, and the higher boost puts greater stress on the clutch and turbo.
The SB2 variant in particular has a reputation for entering limp mode if modifications are made without a proper understanding of the ECU’s tolerances. If you own or are considering an SB2, understanding the remap and limp-mode relationship is important. Our full breakdown of the real-world ownership costs and appeal of the Brabus will help you decide whether the premium is justified for your use case.
Why the Community Still Thrives: The Human Side of the Smart Roadster Review
Perhaps the most striking aspect of two decades of smart roadster reviews is how enthusiastic the community remains. Forums like the Smart Roadster Club in the UK continue to grow in membership despite — or perhaps because of — the car’s age. Owners help one another source discontinued parts, share diagnostic knowledge, and organise track days. There is a generosity of spirit in this community that reflects the car’s character: it attracts people who chose it deliberately, often over more obvious alternatives.
Comparisons with rivals are inevitable, and the Roadster holds its own in ways that statistics alone do not convey. Against the Mazda MX-5, it offers a more exotic mid-engine layout at the cost of some polish and reliability confidence. Our head-to-head comparison with the MX-5 unpacks exactly where each car wins. Against the Lotus Elise, the Roadster is the more accessible, less demanding companion for everyday use, even if the Lotus is the more focused driver’s tool.
The production run ended in 2006 after just over three years, producing around 43,000 units globally. That relative scarcity, combined with the community’s passion for keeping survivors on the road, means that the Smart Roadster has achieved something few budget sports cars manage: genuine collectibility. The full story of how the Roadster came to exist and why production ended is worth reading for context on why these numbers matter so much today.
Frequently Asked Questions
Is the Smart Roadster reliable enough for everyday use?
With proper maintenance, yes. The engine is fundamentally sound, and many owners cover high mileages without major mechanical issues. The areas to watch are water ingress, the SAM unit and the Softouch clutch. A well-maintained 60kW example with a full service history is a reasonable daily proposition for a single-car household without dependents.
What is the best variant of the Smart Roadster to buy?
The 60kW standard model is the most recommended starting point for new owners. It has an oil cooler (unlike the 45kW Lite), sufficient performance for enjoyable driving, and the widest pool of available examples. The Brabus variants offer more power but carry higher risk if the service history is incomplete.
How much do Smart Roadsters cost to maintain?
Routine servicing is inexpensive: the engine is simple, oil capacity is small and consumables are cheap. Unexpected costs tend to involve the soft top, the steering rack or SAM-related electrical faults. Budget roughly £500 to £800 per year for a well-maintained car, more if deferred maintenance needs addressing.
Are Smart Roadster parts still available?
Many mechanical parts remain available through aftermarket suppliers and the Smart parts network. Soft tops, clutch components and engine parts are generally sourceable. Some electrical and trim items are now breaker-yard only. The active owner community and specialist suppliers have significantly extended the car’s viable lifespan beyond what Smart’s parts programme alone would allow.
