Two cars is probably the best way, but in reality I have a Q4 brera which hasn't been used for ages as I have to break my 2.5 year old sons legs to get him in it. I don't mind doing this but he makes a right racket for a few weeks after which I do mind. I imagine i'd have the same problem with the Fiat coupe. Mine is the Ti facelift which I like, but its not rapid however I do like the slow pace now and again. I like the 3.2, but its just the fuel economy, thought about converting to LPG. I had a 156 Gta before the Brera, I might go back again it was epic, the poor Brera wasn't meant to be a gta I know, but its not as quick and uses more fuel. The poor Brera has suffered because of it, mind saying that I still haven't parted with it, but think its going up forsale soon if anyone is interested.
You can't beat the alfa V6's the Brera is my third.
Had a problem with my headlight ballast on the 166's xenons (next car will have standard lights, their not that much better), i'll start a new thread for this as there isn't a replacement part, good old alfa want a full unit at £850.00, I said i'll have four...the jokers.
Back to the turbo thing, sounds a bit more hassle than the overall outcome is worth, it would never be worth as much as I would have to put in....... it has to balance the books. I'll keep a look out to see if anyone elase has done it.
