Or theres always Drive the Ring if you fancy a new Cooper S, tremendous fun arond here.They also have a special offer on at the moment I believe, four laps including fuel/insurance in a n S.The deal gets you one free share in the company which is worth €395.Hire is €399.Best bit is that the share is redeemable in return for another four laps in a Cooper S whenever you want or just keep the share for the future.
I live in Breidscheid and instruct on the Ring (week off this week in preparation for the 24Hr.)
Best advice really is ignore any video games as they are a world apart from real life.The gradients are much more severe and the straights not as long.
All corners here can be negotiated with one application of lock.
Basic rules of thumb is "if you cant see around it, its a VERY late turn in point"
Rear view mirrors, USE them EVERY time BEFORE changing lane, ie making the corners as wide as possible.
No overtaking on the right, it is illegal as this is a German Highway and all highway regulations apply.
Check with your insurance company as to if you're going to be covered-if they tell you no, simply inform them that you should be covered on a German toll road.It has to cover you for the minimum Third Party cover.
Most of all enjoy it, its the best in the world and totally unique.
