I hate to say this but is there a third car that you really like?
The PT cruiser convertible isn't made anymore, that will affect resale value. Both are made by chrysler that is literally on the verge of bankruptcy. If they go under you'll be without the warranty you thought you were getting and you'll have cars that are worth almost nothing when you're ready to sell them.
How about something made by Toyota or Honda. Even if you have to go back to an '05 you'd still be getting a much more reliable vehicle that will cost a lot less in the long run.
