I own a 2003 GT, and it's the best car I've ever owned. The car is amazing in very way. It is a small car, but it's relatively tall which gives you a great driving position.
The great thing about buying a used PT Cruiser is that the depretiation is worse than the reliability. Most people think that high depretiation is bad. But it's only bad if you buy new and sell in a couple years. But if you buy used, you can take advantage of the bad reputation Chrysler has which is NOT applicable to the PT Cruiser. The PT Cruiser reliability is on par with the Japanese, but you can get used Cruisers for a bargain.
I got my 2003 GT with 4,500 miles on it a year ago for $17,000 from CarMax. You can read more about it and see photos at my PT Cruiser photo site at:
