A proper re-trim and re-spray would cost in excess of £7,000 + VAT = £8,400.
So if other works needed doing to put right sins of the past, £19,000 + buyers premium is more than it is worth.
Thanks for telling us.
The most important things, and the biggest costs are those two items. Even an engine re-build is less, if you take the engine out and put it back in yourself, which is relatively easy.
