You might need booster shocks in that Passat. I moved my guns and ammo in the trunk of a car last time I moved (local move) and it took two trips to keep the bumper off the asphalt.
I guess in a wagon you could move the weight more forward. But you get my meaning. Most of us have a LOT of steel/walnut/lead/brass to move, and it's heavier than you think until you try to move it all at once.
