Congrats. I think you have the best wagon built known to man. Is it a 5 speed, or an auto? Hopefully manual, but i am pretty happy with my auto in mine, especially with the Dinan tranny software upgrade. I like the 6 vs. V8 better model because it doesnt have the air suspension in the rear along with the known to fail rear carrier bushings, and the 6'r is more reliable and less costly to run and maintain than my 8. I havent had any issues with mine but it only has 76k on a 2003 model year.
Where do you live? That may determine where yo go for parts...
