Not so Getworth for your vehicle

I submitted details, of the vehicle, which i'm wanting to sell, to this crowd. They assumed the vehicles mileage is high (116,000km over a 151 month period) , which equates to about 9,133km per year. Vehicle has a FSH. Really disappointed, with these armchair vehicle assesors, or whatever they call themselves. We've had previous dealings with Getworth.. however, think this is where the relationship ends
