Call me a party pooper and yes I totally 'get' the M3 and why it was so special but if you gave me a choice of an E30 to drive everyday, I'd take a South African spec 325iS Evo II every time.
I prefer the looks and the sounds. The M3 just looks like it's trying too hard and it never had the performance to cash the cheques it's looks promised. The 325iS was South Africa's M3 since we never got them. In Evo II spec is came with a 2.7 motor and 155kW, few daily things were faster back in 1992.
Maybe I'm just biased because I grew up hearing these all the time. These are very SA spec: M3 wheel or Alpina wheels are always the number 1 choice for any discerning 325iS enthusiast.
