Dont buy a GWM

I own a 2013 GWM Steed 5 2,4 4x4 DC in pristine conditions and now after 3 years I want to trade it in on something more fuel efficient low and behold GWM Dealers does not want to give me a cover in line with Book value but want to knock me and pay me R50 000 less than the book value. So if anybody is listening don't buy this brand they don't have faith in their own products or they are just a bunch of ******.
