I think the jags are beautiful fast luxury cars. Howerver, the beauty of a Mercedes is that spares can be bought at a fairly reasonable cost from online vendors. I don't see many people selling cheaper parts for a jag. To my knowledge they are also not the most DIY friendly cars either.

For a used car, Jag has an excellent bang for buck rating but you should be able to get a W210 Mercedes within your price range.
