need to sell my E39 soon due to unforseen circumstances...Thinking of getting a coupe... (read: midlife crisis)probably will get a bias recommendation here... but thinking of getting the either the z4 or audi TT. Would prefer the Z4 but not that keen on the soft top. heard some horror stories about it...anyone have experience on these cars...?Also anyone knows any dealers with these cars...?p.s., anyone wants to buy my E39?
