depends what you want. as mentioned you gets what you pay for. I bought mine for about 500 quid and it was a proper snotter, chassis patched to ****, every panel dented and uses a pint of oil every 50 miles. but it works, and I like it, it looks ruined but has 'character'. spent about 300 quid ish getting it on the road including new tyres. it is tax free, but it won't be winning any concours comps...
watch out for tyres, they can add a lot to the price and can be a useful bargaining tool to haggle the price down if it needs them
Cripes! How much oil????
My advice is buy a total wreck and spend many hours of quality time with your son restoring it. He will appreciate something he has helped restore.
Cripes! How much oil????
I have put a pint in mine in 18 months - and that is driven daily!
buy the best one your budget will allow
keep in mind
£500- a project on bricks
£1000- a rolling deathtrap
£1500- bulkhead and chassis probably okay, worn engine ect
£2000- a tidy motor with good chassis and bulkhead- maybe 200tdi conversion and t+t
£2000+ one thats been recently restored with galv chassis and full nut and bolt rebuild
