Have the Caddy maxi, last of euro5's, 140bhp, 6 speed, lovely van.
Bought it new back in February, wanted a Transporter but divorce put pay to that. The guy at the garage said I wouldn't regret buying it but didn't think so at the time, however now - love it. Cruise along at 70mph getting about 50 to gallon, cruise at 65mph gets about 56mph, very reliable having said that it was brand new. Plenty of torque, no tow bar fitted so not sure what towing a trailer would be like.
Lots of space in back, can get my mountain bike, road bike in with plenty to spare, only thing I miss is only good for 2 people, did take it to a conversion specialist in Kendal and would be about 3k for side windows, rear seats (2+1) and insulated - so maybe one day, but one day can see myself eventually getting a transporter Kombi.
To sum up, very happy albeit VW know how to charge for extras
Hope that helps
