I love driving my T4 SWB. As someone else said you do tend to drive more chilled out, and the best bit is that all lorry drivers and other vans let you out at junctions as they think your ‘trade.’ (little do they know I wear a suit to work).
Beware older vans cant go into london because of the emissions regulations, its £100 charge if you do want to take it in. Vitos tend to rust just looking at them so id go with a t4 or Trannie.
