I am the proud owner of a 2007 Z4M Coupe. I've had her for about a month. Unbelievable car IMHO. I have been on this forum a while (had a 2004 Z4 Roaster before the MC), but not a regular contributor.
Main reason was the styling of the coupe. I do miss the roadster, but I like the coupe styling better. That was the biggest reason. They are both great and I am fortunate to have gotten to experience both.
