I really like my GTO. It has lots of power and it sounds great in my ears even with the stock exhaust. I didn't make any modifications to mine, everything is stock. The only technical issues I had so far were a water pump replacement at 40k, engine temp gauge problem (electronic part had to be replaced) at 16k. Looks like I got lucky compared to most of GTO owners. A downside is the poor quality of the car. The shifter is wobbly and not precise, the seam on the rear driver side seat is opening up and about to burst open (nobody ever sits on that seat), the paint on the driverside doorhandle is chipping off (pass. side handle had to be repainted already).
LS2 engine, 6-speed manual -> 26 Highway MPG, front bucket seats very comfortable, simple controls, dependable daily driver, rare car -> a lot of head turns and compliments :)
Better quality, heated seats, better transmission, quicker seats (seats move slowly back and forth), Aux In jack, bigger trunk/full spare tire
