The best way to sell your vehicle is quickly and cost effectively. Advertise it in as many places as your budget will allow. It won't sell if potential buyers can't see it for sale. The longer it takes to sell, the more your vehicle will lose value through depreciation and wear and tear, as well as the cost of insurance ,tax and MoT. Be wary of companies promising you a guaranteed sale, with a buyer already waiting. Would you buy something you hadn't seen? If your car is advertised these potential buyers will contact you anyway. We hope this advice is helpful to you and good luck with your sale.
