Im going to see a few LWB tranists tommorrow but i dont really have a clue what to look out for?

Anyone know of any common problems or faults i should be checking for?

Ill be looking at ones from X plates to 2002 models. Looking at spending around £2500-£4000 depending on condition.

It seems every one has damage of some sort in this price bracket. Why do all transits seem like theyve been abused though?

Any advice appreciated.
