Mention of the bill reminds me of the costs involved if you crash at the Nürburgring; not a place to go without insurance which, of course, your own policy doesn't cover.
Cost of crashing on the Nurburgring
These include Armco repairs, safety car attendance, vehicle recovery, track closure, hospital stays and helicopter fees. I recommend avoiding these. If you can't, then the following price-list may help:
Base fee for attendance of armco truck: €150
Removing damaged armco: €10/metre (x2 or x3 or x4 for multiple-height sections)
Replacement armco: €31/metre (x2 or x3 for double/triple height)
Removing damaged armco posts: €5.10 each
Replacing armco post: €39 each
Safety car attendance: €82 per 30 mins (car + 2 people)
Circuit closure: €1,350 per hour
Recovery truck: €250 (inc VAT)
Hospital stay & air ambulance: Let's just say, do NOT go there without travel insurance! (Though a European Health Card - which replaced the E111 - may cover the hospital bit.)
Everything except the recovery truck is then subject to 19% VAT.
The record armco bill I'm aware of is €15,000. That was a car that managed to flatten a very impressive length of armco between the Quiddlebacher Hohe bridge and the crest on the approach to Flugplatz. But even a minor bump can turn into a surprisingly expensive day out.
