New Tires, or New Car?

I managed to placed 2nd today, however my Cooper All-Seasons can't take this abuse.

I'm also getting incredibly bored driving this car, and I've only had it 8 months. 160hp 4cyl, .....yawn.

I like practical, but I hate it. So do I order Falken Azenis, or.... do I buy this guy's 99 Camaro SS and do a 2nd F-body? He's asking pocket change in comparison to what its worth.. 40k miles, mint shape...

..*sigh*
