Dead cars being sold

Just as I was driving out of their Brackengate branch the car blew up the engine head oil mixed with water I can't even explain 😑 these guys are dangerous. Less than 15km the car was already down ****ed up. Couldn't even get chance to reach a mechanic or service shop they didn't even tell me to at least carry the car on my own shoulders to service knowing if I drive it I might just roll out of the road smoking on fire
