When shopping for a Smart Roadster left hand drive or right hand drive example, the steering-wheel position is far from the only consideration. It affects parts availability, legal registration, insurance, driving ergonomics, and even the condition of cars that have crossed borders over the past two decades. With only around 43,000 Roadsters ever built — just 7,251 of those delivered to the UK — the global pool is small, and buyers increasingly source cars from mainland Europe, where the overwhelming majority were sold as LHD. This guide unpacks every practical implication of that choice, so you can buy with confidence regardless of where in the world you live.
How the Smart Roadster Was Distributed — LHD vs RHD from the Factory
Smart built the Roadster between 2003 and 2006 at its Hambach, France facility. The car was sold across most of Europe, and the overwhelming majority of the 43,000 units produced left the factory in left hand drive configuration. Right hand drive production was a relatively small run aimed primarily at the United Kingdom, with minor allocations for Japan, Australia, and a handful of other markets. This numerical imbalance has significant long-term consequences for the used-car market.
Because LHD cars vastly outnumber RHD examples, buyers in the UK and other right-hand-traffic countries sometimes turn to mainland European stock to find low-mileage, well-specified, or rare variant cars — particularly full Brabus models and the 66kW SB2 Brabus. However, importing an LHD Roadster into a RHD country is not a trivial process, and the ergonomic compromise of a left-hooker in a left-hand-traffic country is worth considering carefully before purchase.
From a mechanical standpoint, LHD and RHD cars share identical mid-rear-mounted engines, the same Softouch automated-manual gearbox, and broadly the same electrical architecture. The differences are concentrated in the steering rack, instrument cluster wiring, and a few trim details — all covered below.
Mechanical and Structural Differences Between LHD and RHD Roadsters
The core powertrain — the 698cc three-cylinder turbocharged unit and Softouch transmission — is identical across both configurations. What changes is the steering assembly. The steering rack on the Smart Roadster is a known weak point regardless of drive configuration, but sourcing a replacement for a RHD car can be marginally more involved because fewer RHD racks circulate in the breaker market, which is dominated by LHD European stock.
The instrument cluster and SAM (Signal Acquisition Module) are functionally identical between LHD and RHD cars in terms of electronics, though wiring loom routing differs slightly. If you are considering an ECU remap or electronic modifications, it is reassuring to know that the Bosch MEG 1.1 ECU at the heart of every Smart Roadster is the same unit across all variants and both drive configurations — left hand drive or right hand drive, the ECU hardware and software architecture remain identical, which simplifies tuning and fault diagnosis considerably.
Soft-top mechanisms, bodywork panels, and suspension geometry are also shared. There is no structural asymmetry that meaningfully affects repair costs or parts sourcing at the chassis level.
Registration, Legality, and Practical Considerations for Importing an LHD Roadster
Importing a left hand drive Smart Roadster into the United Kingdom involves Individual Vehicle Approval (IVA) or the simpler Mutual Recognition route if the car already holds a European type approval certificate — which all factory-built Roadsters do. You will need to notify the DVLA, pay any applicable import duty (post-Brexit, this matters for UK buyers purchasing from the EU), and present a valid Certificate of Conformity (CoC). Smart/Mercedes-Benz charge a fee for CoC documents, and tracking one down for a 2003–2006 vehicle can take several weeks.
Speedometer calibration is worth mentioning. UK-market RHD cars display mph as the primary unit. LHD European cars display km/h. Swapping the cluster for a mph-primary unit is possible but adds cost and complexity, and many UK owners of imported LHD cars simply use a GPS speedo app as a workaround.
For buyers in mainland Europe purchasing a RHD example — which occasionally surfaces from UK sellers — the process mirrors the above in reverse, governed by the relevant national authority. In practice, very few RHD Roadsters make the return journey to Europe; the flow is almost entirely from mainland Europe to the UK and other RHD markets.
Insurance is a further consideration. Some UK insurers are reluctant to cover LHD vehicles, or charge a premium. Always confirm cover before purchase, and factor the additional cost into your budget.
Driving an LHD Smart Roadster in a RHD Country — Is It Liveable?
This is the question most buyers agonise over, and the honest answer is: it depends heavily on how you use the car. The Smart Roadster is a low-volume sports car used primarily on B-roads and track days by enthusiasts. In that context, an LHD car is genuinely manageable — overtaking judgement on single-carriageway roads is the main daily inconvenience, and most Roadster owners drive spiritedly rather than routinely overtaking slow vehicles.
Paying at drive-through windows, multi-storey car park ticket machines, and fuel pump card readers all become minor annoyances rather than genuine hardships. Roundabouts in a left-hand-traffic country with an LHD car can feel slightly awkward initially but become second nature within a few weeks of ownership.
The Softouch automated-manual gearbox means there is no clutch pedal to worry about on the wrong side; both driver’s footwells are relatively similar regardless of configuration. The gear-selector paddles on the steering column work identically.
Where LHD ownership becomes more problematic is in urban daily-driver use, particularly if the owner is not an experienced driver of opposite-configuration vehicles. If you plan to use your Roadster as primary transport, a RHD example is strongly preferable — pay the premium.
Variant Availability: Does LHD or RHD Affect Which Model You Can Find?
This is perhaps the most pragmatic section for buyers chasing a specific variant. The performance hierarchy runs from the entry-level 45kW Lite (which lacks an oil cooler and is best avoided for enthusiastic use), through the 60kW standard (the sweet spot for most owners), the 66kW SB2 Brabus, and finally the full 74kW Brabus with its factory bodykit and uprated running gear.
Full Brabus and SB2 Brabus examples were sold in meaningful numbers across mainland Europe, meaning the best-preserved and lowest-mileage performance variants are disproportionately LHD. UK-market allocations of the Brabus were limited, and those that survive command premiums that can push prices firmly into the 12,000–15,000 EUR equivalent bracket. If chasing the highest-performance factory specification matters to you — or if you intend to explore tuning beyond the factory map — the LHD import route may be the only realistic path to a pristine Brabus example. Our ECU remap packages are compatible with all variants and both drive configurations, so the tuning potential is identical regardless of which side the steering wheel sits.
Conversely, if you want a clean, honest 60kW standard car for weekend fun at a reasonable price, the UK RHD market offers enough choice that importing is rarely necessary.
Price Implications — LHD vs RHD in 2025
In broad terms, the Smart Roadster market in 2025 prices cars on condition, mileage, and variant rather than drive configuration. A high-mileage, tired example of either configuration sits in the 7,000–9,000 EUR range; a good, presentable car with a known history commands 9,000–12,000 EUR; and low-mileage or Brabus-spec cars push to 12,000–15,000 EUR and occasionally beyond.
The LHD premium — or rather the RHD premium in the UK — is real but nuanced. In the UK, a like-for-like RHD car typically sells for modestly more than an LHD equivalent because buyers prefer driving on the correct side for local roads, and because insurance is simpler. The gap is rarely dramatic — typically a few hundred pounds on comparable cars — but it is consistent. In mainland Europe, a RHD Roadster occasionally surfaces at a small discount because the domestic buyer pool is narrower.
Factor import costs (CoC, IVA if required, shipping, duty) into any cross-border purchase. For a Roadster sourced from mainland Europe to the UK, these costs can realistically add £500–£1,500 to the landed price, which erodes the apparent price advantage of continental stock.
Summary: Which Should You Buy?
The smart roadster left hand drive vs right hand drive decision ultimately comes down to your location, your intended use, and which specific variant you are chasing. If you live in a right-hand-traffic country and use the car regularly, a RHD example will always be more convenient and easier to insure. If the variant you want — particularly a well-preserved Brabus — only exists in LHD stock at a realistic price, an import can make excellent sense, provided you budget for the registration process and are comfortable with the ergonomic compromise. Mechanically, both configurations are identical where it matters: the engine, ECU, and gearbox are shared, and any specialist work applies equally to both. Buy the best car you can afford, regardless of which side the wheel sits on.
