Had very few issues with my 2006 - and I wasn't easy on it. Two seasons on a 75 shot of nitrous, then at 90,000 miles pulled the nitrous and put the Xcharger on it. When I sold the car it had 203,000 miles on it and was still running mid 12's at the track.
From April 2006 to June 2012 I had to replace a head gasket, at 199,881 miles the thermostat housing went, at 152,000 miles the alternator went out. Other than that, normal maintenance.
