Cars Under 3000 is a family run business in Rayleigh! Our aim is to provide a first class service at an affordable cost, and we don't believe anybody does it quite like us.. We know buying a used car in Essex isn't always easy. And so our aim is to make the process as simple and enjoyable as we possibly can. We don't just want you to come once and leave with a car you're satisfied with. We want to build a relationship, that brings you back time and time again for all your motoring needs.
