that car you test drove sounds a right dog, definitely steer clear of that one mate!
for 14k you will get a very good example, prices have dropped alot recently. in terms of spec there is only two. gt or non gt. for resale definitely get the gt, this comes with leather, electric, heated seats, bose stereo, cruise control and most people spec the 18" rays although if your going to change the wheels you may not be too bothered on this option.
good luck with the Zed hunt!
