I bought it on August 1st 2006. The car was completely bone stock except for the 14" cragar ss rims & cherry bomb exhaust which I had to scrap. The car is fully loaded w/ every available option except for t-tops. I am the 3rd owner & I drove in stock form for 2 years before tearing her down in '08 for modifications and a thorough clean up. Here is what she is today....
