I've got the BMW 328 myself, and a lot of others from various manufacturers in 1/24 scale. I really like Welly's Jaguar S Type, Mercedes CL600, Audi TT coupe...all models not seen in plastic. I've also got a BMW 328Ci coupe that's pretty nice, and I've seen a new M3 by another company that looks good (Veyron has that one). And I'm not averse to stealing Maisto rims for other models...my WRX is using a set of Maisto "aftermarket" BBS rims.
Now if I could just get the time to actually detail one of these models...
