An expenseive car just got more expensive

I purchased a BMW 330d E90 from Inspectacar Gezina 30 days after purchase the car broke its oil cooler the dealership had it replaced but it was done improperly. I took the car for its 1st service and the mechanic informed me of a long list of problems with the car. This amounts to a large amount of money and the dealership is not proving cooperative. Furthermore one of my friends bought his bakkie there and is also having issues with this vehicle but that is his fight. I now have to fork out alot of money because of their shady business practice. Steer clear people I reported this to M.I.O I hope to get results soon.
