I've had my 97 XK8 for 1 year now. I've put on just over 1000 miles (didn't drive it in the winter months). The PO did the timing chains and tensioners. I've done the following:

front brake pads (Akebona),convert top voltage reduction kit,aluminum thermostat housing, coolant level sensor,ABS module repair, Coventry Hornet wheels (sold my old wheels), trunk floor & battery cover carpet, interior car cover, and UltraGauge. Cost about $800

To Do
Third brake light has 1 LED out, clouded rearview mirror,undertray, suspension checked (seems to ride harsh), paint calipers,seat repairs, and a respray.

I did as much of the work as I could with the forums help in my carport.
