If it were a series 3 then you'd struggle selling it, a series 2 is worth more but I think the other chaps are right its well over priced, and it looks as knackered as any unrestored unloved series 2 would be, its probably worth 1/2 of that price.
The 2.8 td is actually a good engine and parts are not hard to get, allthough very expensive, and the power of that engine will rip the box apart, if it allready hasnt done allready.
