where to buy Second hand cars/pickup trucks in shenzhen

Heywo Everyone,

So i’m on the hunt for a second hand work truck so i can truck tooling around, but i cant find anywhere that might sell used cars. Is there such thing as a second hand car yard in China??

I’ve been to a few new car dealers but they only offer spanking new cars and the staff were as much use as a blow up dart board.

Anyone have any ideas, places or websites in shenzhen?? B-)

Cheers

Stevie
