Hows about, a compromise then...
Find a G60 Corrado & mod it a little.
My m8 has one running close to 200BHP & its amazingly rapid i just tell you!
The sound you get from the supercharger is amazing, bit its also v v expensive to run/maintain.
All this said & done, maybee im a little biased now as i conveted to Audi, but i did first have an e30 325iSE
Still said, that old e30 i had was one of the smoothest cars, if not THE smoothest cars i have ever owned. This said, i owned a Fiat Coupe 16V non turbo before i got the e30, the Fiat was just a complete turd & a bad choice, was sooooo glad to see it go back to the finance company after i got pissed off with it costing a fortune & not going far without breaking!
