You conveniently forgot the California/Portofino... It can do anything a 911 can do but on top of it it looks good and is fun to drive, it has a good size trunk and is coupe/convertible... Plus it has somewhat better resale value. The California is the car we use the most in the summer. We can’t seem to be able to get rid of it and replace whereas I would not even think of buying at 911 TT convertible because they don't look that good, they are somewhat common mixed in all the 911, they have the same interior as a $60k Boxster and more importantly once optioned properly are vastly overpriced. Plus they don’t sound that good (tone and way too quiet). A convertible GT3 with rear seats and no wing would solve a lot of the issues.

The Ferrari even has the same flaw as the 911: eventually the rear seats are too small.
