Have a 997.2 GT3 and a 6mt 08 M3.
M3 blows the GT3 away as a comfortable daily driver.
Do not like driving the GT3 on the highway at 70mph....too loud it blows.
Would think that the 996 GT3 would also not be a good daily driver.
The inside of the 997.2 GT3 blows the M3 away. Handling and performance no comparison.......GT3 is like a plush race like car for the street, M3 is a cushy sedan.
