£1500, wow! Now that is crazy! I've had this happen a few times now and estimates have ranged from 5k to well over 20k.
The best one was a little while back. I was approached at a garage when filling up and the chap asked exactly the same, what did you pay? Mine was £7000 and completely standard when purchased and mods, wheels excluded, have come to about 3.5k. When he saw the car it looked exactly as below but on a private plate, hiding the age. At first he thought it was a Porshe and pretty much brand new and when I said it was a Nissan and I'd had it for 5 years he still thought it was worth around 18k!
Its definitely interesting hearing what other people think. My cars been mistaken for a Porshe more times than I can count and by far the best.... a Bugatti lmao.
They do say beauty is in the eye of the beholder and I've no doubt there are many peeps out there that would think your motor is worth 10 or more times what that guy said and many who would think our cars are scrap. I wouldn't be insulted by the valuation. Laugh it off Nice Zed btw
