that is fantastic. Hope I never need one. A local guy has a small compact (hyundai getz i think) & his chair is so light he lifts it over his head onto a rack & the chair clicks down to secure it.One of our local servos gives the old service treatment & fills his car etc so he remains in drivers seat. He looks about as mobile as that chap. The VW must have filler on passenger side or it could cause issues though it seems to only needs, at most, the width of the drivers door.
It does take up a lot of room but for independance it's all good.
