I wasn't sure if it was new or old. A newer GTO shouldn't be needing this kind of attention unless it was used hard, especially for a one owner. If its a new age GTO and its needing this that and the other thing... Triple the deposit funds to the GTO Escrow account.
** OK I looked ..... its an '05 ... guess I should have looked first before rendering an opinion -)
Mine has 40K. Just a battery and a few warranted parts (BCM, door actuator, rear springs, PCM, rear seat covers, rear end) mine was new as well and one owner. These cars have their share of issues. If you're lucky they fail under warranty, if not..... ouch. Many take pride of low miles... with the reported issues with these cars, its wise to drive them good and utilize the warranty if needed. Having a car with a few hundred miles that is way past warranty and then driving it good, the "normal" reported issues begin happening and repair is on your dime instead of GM. There are too many issues with this car as it is and at 59K miles with issues happening is inexcusable like most cars.
