The car is way tighter than the regular C6 - not a rattle, creak or pop. The fixed roof has fixed a flex issue I didn't realize the regular C6 had. It's also faster than snot. There's no horsing around on the street with this one...one wrong move, and you're in the weeds.
Otherwise it's perfectly able to cruise and profile, just like the C5s and 6s. Road fuel mileage started out at <18 mpg, but was at >27 by the time I got home. The motor was, obviously, waaaaaay tight. I dumped the oil as soon as I got home, and both sump drain plug magnets were very caked with fine iron powder, and the oil was black! With 8 quarts of Royal Purple, it now runs loose, and revs quickly. An early oil change is a good idea on any Vette, but seems really important on the Z06.
On the road nobody pays attention to the RF edition - except other Vette drivers. I met three neighbors (all Vette owners) who, all of a sudden, needed to welcome me to the "hood" - I've lived here 4 years.
All in all, it's probably a better driver than the regular C6. Just my opinion.
