Just a tip Red as I've sold a few, inside, make sure its clean ( Do you smoke/) wash/polish outside, there is a product for the tyres called Tyre Sheen this shines up the tyres, is the car Taxed / tested? the longer these are in force the better the sale, history? does the cars book show its history? how many owners? do not hand the cars keys over until you have the CASH, if its a cheque keep the car until its clear, do not let the person take the car out for a run on their own or without insurance. if the car is clean as you say it will sell, what make is it?
