The Freestyle was first sold for the 2005 model year, and it was discontinued following the 2007 model year. It will be replaced by the Taurus X, which I can only imagine is some sort of bigger, more "extreme" version of the luxury sedan Taurus that will be making a comeback this year. I know, you're probably already planning to camp out the dealership to make sure you're first in line. Uggh.
Like the Five Hundred (which is the car that will be renamed the Taurus), the Freestyle is based on the D3 platform. It has a front engine and front wheel drive. It also comes in an all wheel drive model that has been very popular with buyers. The engine is a 203 horsepower V6. The new Taurus X is not significantly different than the current Freestyle.
These SUVs are readily available on the market today. You can get decent deals if you buy from dealerships that sell their excess supply on eBay.
