Couple of options
spend £500 to keep a van you know to be mechanically sound on the road .
or
use the £500 to go towards another van (buying someone elses problems)
Reason(s) for failure

clean up and apply grease or change the flexi if it is really badExhaust has a major leak of exhaust gases down pipe (7.1.2)
check gaskets/get it welded/put new 1 on (they dont last forever)Vehicle structure excessively corroded within 30cm of towbar mounting rear cross member (6.6.6)
