The guy is mistaken about the F1 engine, it was designed specifically for the F1 by BMW, not “just a standard BMW motor” as he claimed.
On a much lower scale, I just got my 12C back from service. As I was picking it up, my wife said “what’s wrong with the headlights?” I hadn’t noticed, but both units had fungus growing inside them as a result of moisture getting inside. I asked how much to fix, and the service manager said $10,000! Not covered by warranty either! After a bit of “back and forth” with Woking about why should owners pay for an obvious design/ manufacturing defect, It’s back in the shop getting the headlights fixed for free.....
