Buying a M6 with a service history (in German), need reassurance

[CarlessBoi]

Basically title, attached is the PDF document (in German) for the said car.

I will be buying the car in Germany, the car will be sent to MOT (TÜV) for strict check of anything less with the car.

MY2013, accident car (bumper, not affecting frame and axle), in Germany since 2015, 70k km on odometer. Description of condition of car is done and appraised by BMW München at 70k km.

Should I be worried of anything? I am dead set to buy this car just need more reassurance. Any help will be much appreciated

Why did they do it?? Has the engine been overheated? Not a very clear story.
Why does history only start at 21,000 kilometers?
Where was the car before?
Is this a German car or an export version?

The car is a US-Export which had an accident there and been fixed since.

After a long self-guessing I plan to follow my gut and say this is not it. I am now planning to get myself a BMW M4 instead.

Thank you very much for your reply

Going to a M4 from wanting a M6 is a huge difference.

Well I am only for the BMW M (due to personal reasons) and other M6 is way out of my budget.

Also an advantage due to BMW mastering their 6 cyl engines.

I have no idea what alternative I have to something as beautiful as M6, but also fun to drive while maintaining a lower used price.
