Character

M135 1.3/1.5

"ForTwo/ForFour 453. Mitsubishi 3A9 engine (Mirage/Space Star). NA 1.0 (71hp) and 1.3 (109hp). Brabus 1.5 turbo (177hp) rare. Simple, reliable for what it is. Timing chain. CVT on ForTwo can be jerky. Better than old M132."

H4B (SCe 1.0)

"Renault H4B in a Smart box. Slow but honest. Simple 3-cyl, no turbo drama. Perfect city runabout."
