Two flaws I`ve noticed.
First, I don`t think it`s ever explained why such a wealthy Arabian sheik would take a vacation or whatever he`s doing in such a remote place. I find it very unlikely that a filthy rich Arabian would ever just spend time there for no reason, and that reason is never explained.
Secondly, one would think that they would inspect the car since they knew that Blodstrupmoen had broken into the garage. And even more so before the race, the car should be inspected and checked that everything`s okay.
But since they obviously didn`t know about the damage being done to the car, it looks that they hadn`t checked the car at all before the race. I also find that very unlikely.
Correct me if I`m wrong.
