From what I've heard the concept coupe is just a concept. With the all new Jetta sedan for 2011 I would hold off buying a 2010 because the resale will go down quite a bit once the new cars come out and I'm guessing the new one will have NVH improvements like the mk6 Golf. If you are going to hold onto the car for 10 years and can find a great deal it wouldn't make a difference but it sounds like you've made up your mind. They're supposed to have a TDI as well.
