Smart Models
Smart (Swatch Mercedes ART) revolutionized urban mobility with the original Fortwo. While owned by Mercedes-Benz, these cars have their own unique set of mechanical challenges, primarily centered around their specialized automated manual transmissions and compact engine packaging. In the UK, they are tax-efficient and easy to park, but maintenance can be surprisingly expensive due to the tight engine access and sensitivity to water ingress.
Smart Forfour (453)
The four-door version of the 453. Like the Fortwo, it is rear-engined and shares parts with the Renault Twingo. It has an incredibly small turning circle for its size.
Smart Fortwo (453)
Shared platform with the Renault Twingo. This model offers a much better ride and the option of a proper manual gearbox or a dual-clutch (Twinamic) transmission.
Smart Fortwo (451)
The 451 generation moved to a 1.0L Mitsubishi-sourced engine (naturally aspirated or turbo). It is significantly more robust than the 450 but introduced its own unique issues, particularly with the MHD system.
Smart Forfour (454)
A front-engined, front-wheel-drive Smart based on the Mitsubishi Colt. Much more conventional than other Smarts, but the automated manual version still has actuator issues.
Smart Roadster (452)
A lightweight, fun sports car that shares many components with the 450 Fortwo. It is famous for its handling and infamous for its leaks.
Smart Fortwo (450)
The original Fortwo is tiny and clever, but it is also the most fragile. It uses a 600cc or 700cc turbocharged 3-cylinder engine. In the UK, many have succumbed to engine wear or electrical "death by water," making a well-maintained example a rare find.
