The 2000 XKR was well under $30K when I bought it two years ago (after attempting to buy a GTO from multiple GM dealers and leaving in disgust). Ironically, BOTH are still more reliable than most of my neighbors' domestic cars. I *know* the 87 XJ6 is screwed together better *now*, with 230K on the clock, than my neighbor's Impala is, for example.
It's a pretty sad commentary when a 20 year old Jaguar is more reliable than a new domestic product.
