Untrusted secondhand vehicle sales

Would not recommend Klerksdorp Mega Theron Car sales for any vehicle deals. Dishonesty. Sold me a Modified VW which was tampered with as well the vehicle i paid for cash on 28 May and still have not received the log book or registration documents as what i paid for. These guys are not trust worthy. I took the vehicle on delivery to VW as it was over fuelling and could not select gears.
