As the number of GT's becomes fewer each year and the OEM parts become more scarce, what parts make sense to buy and hold for my personal car? Or...do you think there will ever be a real shortage of parts available at a reasonable price? I know we have experienced some steep price increases on some parts I.e. Headlights, now even FRPP mufflers new from distributors but what parts make sense to buy and hold for later for my personal car? Particularly wear items or maintenance items?
