Nigel,
The low mileage isn't really a selling point to anyone who would actually want to use the car regularly. There are multiple threads discussing this on the forum, a higher mileage car is arguably worth more than a car with low miles, again those that have done their research will know this. The PRV engine in the DeLorean really does not take well to sitting.
I note from the pictures that the car has original fuel lines, is it also running original brake lines and original coolant hoses as well? There is no note of these items having been replaced in the sales spiel. Have the trailing arm bolts and lower ball joints been replaced? Clutch line upgraded to stainless braided? It's riding high at the front so still has the original moon buggy front springs fitted.
Regarding the centre console, my comment was more in despair that someones idea of a 'fix' was to put a self tapping screw through a no longer available part. The rest of the interior also appears to be sun faded with multiple interior parts displaying different shades of grey (not fifty shades though
)
I am not in the market for a car (I already own one), but I suspect you will be sat on it for sometime at a £40k asking price. Of course you could get lucky and have someone come along who doesn't take the time to do any reading up on these cars.
All the best with the sale.
