Purchase advice R8 V10

Moin, I’m looking for an R8 V10 roadster, not older than two years and max 20,000 km. It’s usually around 150.000€. Then I found one at Auto Scout EZ 04/18 with less than 8000 km on the clock. Only 106,000. Visually exactly as I want it to have. V10 540PS. But if that’s so cheap, it also has hooks. US import vehicle, ok, no problem with it. He had an accident damage, from which one can see or notice nothing more today, but unfortunately not documented, one can or does not want me The first look at the tires. Production at the end of 2016. Profile v/h about 5mm. Does this fit together with EZ 04/18 and <8000 km? Then test drive. Everything great, chassis engine (automatic) gearbox. Only the brakes (steel) rub easily. The dealer told me that at 2000 km the brake discs had been changed before ?? The scratching was not so strong now that it would be alarming. But according to all experience it will always be possible to say what exactly was affected. now the question: Would you buy it? Is this brake scrubbing often on the R8?
