All the above reasons is why I changed to a boxster, apart from one important one, the exhaust noise.
Nothing can compare to the noise of an almost straight through exhaust connected to a thundering V8 lump. The pops and bangs on the overrun is awesome. That's the only thing I miss about the TVR.
So far I have fitted a double din touchscreen cd/rad/satnav/dvd player, sports back box with sports headers ready to go on soon. New discs/pads and clear rear lights which I really like
