alot of wishing and hoping never makes for good business decisions. Most important aspects on Cobra is paint and body, it is the most expensive to address. Your tires are shot at 6 years, sure drive around the block and do some burn downs but replace. Why replace ball joints and bushings????????? I got 45 year old cars with 200k miles with original ball joints and bushings. I would change
oil, check coolant and drive it.
