When I bought my 2000S, I knew what needed to be done after driving and looking the car over. A one owner in pristine condition and a PCA decal on the window sold me. Didn't have time for a PPI, other buyers lining up to buy. I have spent a bout $1500, new tires, new rotors and pads, brake flush, 60 miles service plus the TIP. I did everything but the tires.
