Just checking my local Gumtree (UK craigslist) again and its insane how many nice cars you can get for under a grand just in the area. I picked this 3.2l Signum just as an example. Low miles, decent performance (if it really has a manual, same engine as in the early 1st gen CTS btw), good condition, very nicely equipped, generally a great car (and a hatchback/wagon!).
