I feel your pain, it’s a bloody nightmare. I’ve sold a number of cars that are desirable to a certain demographic and every time was a total pita. I was very clear about the ‘no insurance, no ID, no drive’ status but I still had stand offs with a few people.
In fairness I’d never buy a car without test driving, but I wouldn’t (and frequently haven’t) bothered with that unless the rest of the car checks out first. But it’s hard to be accommodating and not come across as an awkward wazzock.
Selling a 172 cup was pretty bad, but the worst was my other half’s DC2 integra. There was some serious vetting of the prospective ‘buyers’, but I still made a poor call and ended up passenger to one of the most terrifying drivers I’ve ever had the misfortune of sharing a vehicle with.
Its one of the many reasons I’ll never sell my RX7 as a whole car, and will go through the ballache of breaking it instead.
