The Alpina is finally back home - with the garage only left to finalise the bill to the warranty company (copy to me) and the fluids bill to me. First indication are around the 10-12k mark to the warranty company!
The bonus for me is that the car was nudging towards a service - and that has now been done - a full inspection obviously. This means the next oil change is due in 24,000km and an inspection in 60,000km. So in theory it should be back to being cheap to run - apart from the 1,500chf warranty renewal cost.
