Land Rover 110 td5.
Our system has been in development for 8 years. It has loads of advantages over a van and very few disadvantages.
We have been running Land Rovers for over 10 years. I still have the first one we bought. See what kind of nick your van is in 10 years time, not good I'll bet. If I sold my first Landy tomorrow (it would sell within an hour what with the weather) I'd get more than 2x what I paid for it, probably more than 3x.
Simples.
