I got mine for £150 plus my 4.4fd in px, but it was higher mileage than yours. I'd say 350 quid? Even tho it is a very low mileage item I find that people don't want used stuff unless it is significantly cheaper than new. When I was trying to sell my coilovers that I'd had for a couple years but never used them people would only offer around 50% of what I paid for them. In the end I decided to keep them, but I do get where folk are coming from, I also wouldn't buy used for the sake of saving 50 quid on a £500 item.
