What happened to "gundamsi's" question? Oh well, here's my answer. No, I've not noticed any mfg. problems with the coupe. Normal, very small stuff. One side of my door trim was sticking up; a service mgr. was able to use a paper clip (yes, really!), and work his way under the rubber and secure it down. It's been trouble free for about 6,000 miles so I guess it's a permanent fix.
Also, had the clicking sound from the rear axle; dealer lubed and retorqued bolts on axle and trailing arms, all under warranty. No more clicking noise. That's it.[^]
Re ksw: if you think buying a BMW 330i coupe is an alternative to the G35 for ride, comfort, looks, extras/accessories, quality, prestige, handling, performance, etc. go ahead.[

] For the dollars, I don't agree. Thus, I own a 6mt G coupe. Don't knock the G tho. It's less dollars and, from my ownership of almost 12,000 miles, a very good car in many respects for what I paid for it.
Are there things I'd change on it, if money were no object? Yes. Are there things I'd change on the BMW if money were no object? Yes. And starting price would be one of them.[boink]
Your choice, but I expect we'll be seeing you in a BMW. Anyone who thinks that's the comparable car doesn't really want a G, in my opinion.[
