Frankly, finding this meaty Jag with its supercharged 4.2-liter V8 under the $10,000 threshold blew our minds. It's not just a few clicks under either, and for the record, we checked NADA pricing in the Detroit area as well as Los Angeles and came back with the same $8,675 figure. This car was over $60,000 brand new, and at a whopping 420 horsepower, it's the second most powerful car on the list. However, browsing customer reviews at Edmunds.com shows the risk of owning a high-end, high-performance, 10-year-old Jag. If you can find one that's been maintained well, it could be a hell of a bargain.
