Right now is probably a good time to purchase a new auto/truck/suv...GM currently has a voucher program where the govt will give up to 4500 for a used car trade in the chevy dealers are pushing it alot now...plus hybrid's are giving up to 5000-6000 rebates for many different brands and hybrid suv's too...
0% interest offered or 3500 cash back/ 7 yr financing too...all now are offerring a plan with a new purchase if you loose your job the pmts will be made up to 6-12 mths/varies with who you buy from...it will not affect your credit rating...some have you can give the car back too.
I know a lady who wanted a decked out chevy tahoe and she waited and one of the chevy dealerships lost their dealership and she bought it for 23,000 it listed for 49,000. Chrysler/dodge/jeep are selling well below cost.
Ford is really giving some great deals. Foreign sales are up, they have deals to, but I prefer to keep american workers with their jobs with the old standard ford/chevy...this is a personal choice, who knows what the future will bring...to each his/her own. It is what I grew up with, and others will make their own choices, so this is not a debate/just offerring what is out there.
Check the web sites, newspapers, and call the dealerships. They will tell you what programs/incentives they have now.
Good luck with your search and test drive it overnight if you are serious about a certain vehicle...also ride in the back seat too/as we bought a new ford mustang GT red convertible some years back (before my disabilities took over my life) and I sat in the back seat after we bought it...no leg room...but what a slick fast beauty it was! Kept it a few yrs and traded for a eddie bauer explorer...love it and gets good gas mileage cause I drive it like a little ol' lady, haha.
