I tried the We Want Any Car etc. Websites for a valuation on the Bongo. Reg. no. not recognised. Probably a spares or repair one and as Nick says probably nearer to £1600 than £16.000!
If you want to buy one of a similar age there's one for sale with a Gosport motor home trader at £14,000. Motor homes, like Morgans, it seems, hold their value. No doubt motor home fans would find Morgan values as inexplicable as some on here find the value of motor homes.
