Seems like the general opinion is;
Original is best
Chassis doors and bulkhead are prime rust spots
go and view, checker plate can hide a lot and mods are often hiding problems (or causing them)
200tdi and 300 tdi are good but 300 easier to get parts
There seem to be a few companies selling tarted up ones around the 10 grand mark but some of the pictures show the chassis oversprayed with stone chip and some dodgy looking resprays too, so I'm assuming probably good to give a miss to those too
I think I'm going to up my budget and find one with a refurbed or good chassis and then do the mods myself after reading all the posts on the forum, or maybe find one from someone reputable on here!! (hint hint!!)
