there isn't one.more interested in performance difference between the 172 and 200!
look again. People are sayin they are more modern and feel better made. But no one is sayin there is a big performance difference.Looking at the comments above everyone seems to think its a good upgrade! So think it is going to happen soon tbh
generally they are pretty good and parts are quite readily available.On the topic of the m3 tho we have a few customers in the garage that own then and the running costs (not talking mpg) but general repairs and maintenance are just silly! So I would much rather have a small hot hatch than an m3 everyday of the week! Personal opinion tho of course!
