Know ur engines

Awesome selection of cars, but be very clear and knowledgeable about engines, as u buy from them as if u buying from a private person, just that they don't have the experience or expertise wrt the specific vehicle, all the sales person is, is a admin clerk doing your application, and they always seem tooooo busy to deal with all ur Obvious questions, eg would u buy this car, and responses are very random, so don't expect a detailed response, all they provide is a dekra report,
