By "out the door" do you mean after tax and license fees in CA? If so, then 22k is out of the question from a dealer. Unless you are the grand master haggler of all master hagglers, then maybe 24k.
5 spd or auto is a personal preference thing, and I would personally never consider an auto for this car since it takes away about 90% of the fun involved in driving this car. But an auto may be suitable for some peoples' tastes.
Looks like a nice one. You probably won't get to take it home for 22k but you can get closer by telling them you will give them 500 over invoice. Trade in on this one is: Fair-$18,720, Good-$20,905 & Excellent-$22,125. I can guaranty they didn't give some guy 22k for his trade in and I know they like to give less than Fair so 500 over would put you a lot closer to 22k OTD
