Car deals, and car value

My Jetta is getting long in the tooth. We have been considering a replacement for a while and have saved up the cash to pay for a new car. Macro-economic forces have caused the bottom to drop out of the US new car market, meaning lots of dealers have cars on their lots. It is not unheard of to score deals for $5-7,000 below market value on new cars. We are on the prowl.
