Alpine on here was looking to buy a 1.4 petrol, just a few posts down from this one. As a guide on price, they do vary a lot but they only sell around the £2k mark. Dealers put all sorts of prices on the screen and they are there for months. On Facebook market place last year there is a guy selling a 1.6 diesel with a sunroof for £5000 in a private sale, and he refused my then offer of £2500. Guess what? got one for £2250 within a month and his is still up for sale and overpriced at £3500 a year later. £2000 is a starting point, a bit more if it has nice wheels, leather and navetc , a bit less if it is a base model with none of that stuff and no history. HTH
