How many versions of the E30 M3 convertible were there?
There were three versions of the E30 M3 convertible, all in left-hand drive and all built to European specification. Cars produced in 1988 and 1989 use the standard 2.3-liter S14 engine in either non-catalyst (200 hp) or catalyst (195 hp) form. After nearly a year out of production, a second batch of catalyst-equipped cars was assembled starting in March, 1990. These have the later 215-hp version of the S14 engine.
