Thank you everyone for the helpful input and experiences. I only have about $4500 to spend and I really want a 99+ GTP. Unfortunatley, most of them I'm finding have about 130k miles on them. I know that is relatively high, but not for these motors, but still with a car with that miles what should I look/listen for, or should I just rely on receipts?

Also, I understand its pretty important to change the supercharger oil once a year, so is there a way to check if the car has had that maintenance besides receipts? IE- anything to look for or listen to under the hood.

Sorry for all these questions - It's just I really like to research and hear about actual consumer's experiences with the vehicles so I know what to look for before purchasing one! I never used to research and had a pretty bad experience - so now I always do!

Thanks everyone so far!
