Forget the Navigation ...... useless! There are no current updates for navigation available. Better to get a Garmin portable and use that. Your budget of 20K is OK right now ..... You should be able to p/u a decent SRT for that. Coupes will be less money that roadsters! There seems to be an up-tick on SRT prices occuring at this time for low mileage cars. Low mileage meaning 10K or less. Research the forums, learn about this great car, and then be picky. Get the SRT if you can, rather then the n/a. N/As are better in the twisties, but for sheer power the SRT is the way to go! Be aware that the tires on these cars generally don't get the mileage you might be accustomed to on your daily drivers. If you get 20K out of a rear set that would be great. Most of the cars came with Michelin PS2's, which are "summer" tires, and are soft, so they wear faster. If you plan on driving during the winter, they are terrible on snow and ice. You'll probable need winter tires then. You probably will get a lot of feedback from the people on this forum, and the search for the right car is an enjoyable task. Wish you luck ..... Have fun
