I put 6000 km on my HTC since March. Pretty much driving it daily.
Two CELs but no real problem. Goes away after a couple of start up.
Roof pops and creaks which I dont like.
Ride pretty firm (probably also exaggerated by roads here in MTL).
Love the sound, if you dont like the drone just put it Tour on the highway.
Could use more torque down low (also probably exaggerated by the extra weight of the HTC) but it pulls like a train once pass 4k RPM. Definitely needed to adjust my driving style.
Tested drove a 992.1 Carrera s and it feels faster in most situation because of the turbo torque.
If you like your SR and want something more, get an E-Ray. If you want to experience a Ferrari at a discount, get a z06. The latter is what I wanted and now I am actually considering getting an E-Ray by the end of next year.
