If you're still considering a Passat, I drove one the other week (not W-engined unforch). Feels like a much smaller car around town due to the auto box and very light steering but the the interior quality is shit. Creaking plastic and fake chrome all over the place.
What would people think that this would be worth in three years with a) 15,000 more miles on it, and the MB service history maintained?
And what else might fit the auto/estate/sufficient power requirements for ~£550/month/three years?
