"Rover Maestro" - it was an MG Maestro.
With a 0-62mph time of 16.8 seconds (older ones were even slower!) the diesel Smart is one of the slowest cars you can buy. But, bizarrely, from the wheel it feels strangely rapid and fun to drive. Even if evidence points to the contrary! DT
... WTF?
It's the half a Bugatti Veyron engine under the bonnet (minus the turbochargers).
... and every other part of the engine!!!
