Seriously Not Impressed! Klerksdorp

I decided to sell my vehicle on we buy cars Klerkdorp. What a Mistake!!! The Meeting Was for 2pm he arrived at 3pm. The Evaluation I Got for my vehicle was R25K As it is n old vehicle I decided Ok Fair enough as i will ise the cash to ad on a deposit For a new Vehicle But as they arrive for the vehicle the Evaluation dropped To R7k Seriously? Took The vehicle for a drive from stilfontein towards Klerkdorp To test drive but nobody said anything about being the Fastest vehicle on the road and kept looking to the back window for some reason while driving On the N12. If i get any fines I'll be sure that Person is going to be liable for it. And so as we stopped from our quick drive this person tells me must go look underneath the vehicle, in the front, while the vehicle is placed in first gear and idling at 2000rpm. What do you think wat will happen if your foot slips Anton - accident's happens very quickly, i have a responsibility .
