Mine took about 10 days to sell. Maybe I priced it too low, who knows, but I was well chuffed with the buyer. A proper car guy, he even took me out for a spin in his MX5 NC which he had arrived in as I hadn't been out in one before!
I got what I wanted for mine, rather than spending months trying to convince a potential buyer to pay a bit more.
Ultimately a car is worth what someone is willing to pay, no matter how incredulous other people may be of it. And for sure, there is some value in a car that is cheap to insure, no M tax to maintain, is still very quick, looks fantastic, big capacity not turbo'd. It ticks many boxes.
