Just rolled over 13,000 miles. The rear tire and sprocket were toast at 7,800 miles and I just installed the 4th set of front tires. The drive belt appears unworn and will probably outlast the rest of the car. The afore mentioned items can't really be considered problems as they are "consumables". The only real issues I have had with the rig was bump steer, the voltage regulator and a fuel pump. Did I mention understeer?
Given all those niggles, there is nothing else with a steering wheel that I would rather be driving on a sunny day.
