Tested a 200 at the weekend. Really didn't want to like it but... Compared to my 182 it is, honest to god, about 1000% better. Much better build quality, almost german in feel. Useable rear seats, unlike the 182. A nice clutch, unlike the 182. An excellent gear box, short throw and positive, pleasure to use. The chassis is terrifc, there's bags of grip and plenty of power too. Not perhaps quite as much immediate response as the 182, and electric power steering means it doesn't have quite as much feeling, but as an overall package its a far, far better car than the 182. You can see that it was designed at a time when people had money to spend and to compete with the mini, which really moved the game on.
Overall, for what i need it for - one car for day to day use with 4 seats and to do half a dozen track days per year, it's a perfect car and I want one badly. Just got the missus to win round!
Can't really comment on the v6 as I've not driven one and need 4 seats anyway, but when a similar price can get a z4m, I don't think I'd ever consider buying one.
200 for me. In black, with black speedlines, recaros and the cup spoiler. Looks pretty good in the metal!
