I had a 1.9 TDi for a while, great van. Unfortunately didn’t use the dealer for anything other than the purchase so cant help there.
Good to drive (for a van), comfy for the driver, horrendous for a passenger (if over 5’9″ anyway), rear suspension is less complex than what Charlton Heston had in Ben Hurr, tail gate ftw as it lifts to a really good height to use for shelter, fuel economy is good, had 6 bikes (mix of dh and trail) in mine + kit with no more than front wheels off. Would have again.
With the bikes at a slight angle I could easily get a couple of fully built DH bikes in, so make sure to have a bit of a play around if/when you get it. Take the bike to the dealer if you haven’t yet
