Thank you for the exhaust info. Can you tell me anything more? I'm seeing 2008 GTs listed everywhere from $65,000 to over $100,000. Are there different models? What should I look for? What should I avoid? With cars listed in the mid-60's, is it possible they might hit the hi-50's next Spring?Great cars and pretty much bulletproof. If you get either the GT or QP put the GTS exhaust on it and you will never be disappointed.
