I had over 100,000 miles on my Land Rover Discovery, I beat the ever living crap out of it. It NEVER EVER needed an alinement. No junk. Therefore I believe it does have something to do with how a vehicle is built. My 2006 Subaru Outback Turbo was always pulling hard to the right and the dealer could never fix it. They declared it "normal" . I sold that car in less than six months and will never buy one again. Fortunately I have had no problems with my H3 and I love it! P.S. My Jeep was always out of alinement, but I still almost cried when I sold it. Just my two cents.
