last dive I went it was 22 € for 1 lap.
Nürburgring Grand Prix Circuit Track Days are 30 € for 20 minutes.
the thing about all that video game portations is, that most corners aren't like the ones in real life, not even slightly. the most accurate virtual Nordschleife I've seen is in GT-R Evolution Racing Simulator.....not very good looking, but the corners are better.
here's a video of the game I made with my Logitech G25 wheel
GT-R Evolution BMW Z4 Coupe VLN - Car Videos on StreetFire
In this game you'll get a feeling of how bumpy that road actually is.....at the end of Wippermann section (google for it lol) (video time 7:26) you have so much positive G you barely can watch over your dashboard.....at the Pflanzgarten section (8:0

and 3 turns later (8:20) you'll have so much negative G you'll only see your headliner lol. its crazy
