That sounds overly expensive Simpiwe, depending on what is done to the car. My dad pays R1800 for his Corolla (2010 2.0 d4d), and then they even check silly things like your remote battery. I was quoted about the same for my old Lexus. These are all minor services, ie no brakes or cambelts and things.
I know my hate for VW is irrational and founded on too little info with the wrong models etc, but I can't help being very negative about the brand. If you check hellopeter.com you'll read some shocking complaints with VW. I'm talking borderline criminal behaviour and dishonesty.
On the other hand, a friend was quoted R45 000 for a new turbo on his Nissan Micra! The quote then went down to R20 000, then R15 000, and when they realised they were going to lose the business completely, they ended on R7500.
R45 000 should get you a second-hand Nissan GTR motor, including the turbos or a second-hand Micra for that matter?
