Unless you want another vehicle just keep the car. If you're looking to buy new any automaker is going to push the old "well you know what happened in Japan" crap.
My buddy was trying to buy a VW this past weekend and the dealership was talking about the huge demand they have now that Japan had the disaster. Because of this they "have" to keep prices high or else they would run out of cars in a single weekend.
I was like WTF...we're talking about a Jetta you have on the lot and you've got 11 more just like it. We're the ONLY people that have been here in the past 1.5 hours.
We just walked out.
