We buy cars

Hi guys. I went in to we buy cars and looked at a double cab. I app**** for finance with alot of paperwork and time. Vehicle is marked at R143 000. I took it for a drive and all seems well, got approved from Wesbank, family is happy. Then they say it has to go for a road worthy test, now they require me to fit the bill of R22 000 worth of work plus add a motor warranty of R9800 before taking the vehicle. So the new price of vehicle is sitting at R164 800. THAT SHOULD OF BEEN THE PRICE INITIALLY. ALOT OF TIME BEING WASTED.
