My first-ever virtual lap of the Nürburgring was a 7'30" if I recall correctly...
...with the Porsche Carrera GT on Project Gotham Racing 2, that is.

That was my first-ever lap in a PGR-series game, too...I wasn't the one who owned the game or X-BOX.
I knew about the course before I did that lap, though...I think my first exposure to the name was a rumor of a really long, crazy, German track in Grand Prix Legends...after that, I looked it up, found Nurburgring.de, read about the course, downloaded some clips off of the internet...I've been hooked ever since.
Driving the course in GT4 was definitely a wake-up call. It was the very first thing I did in the game -- an arcade-mode race with an E60 M5. I wasn't familiar with GT4's screwy physics, so I crashed. A lot. Having only raced PGR2's freakishly-huge Nürburgring didn't help either, even though I already knew that the real course was smaller. Anyway, by the time I got to the two Nürburgring license tests, I was able to just breeze through them.
The most magical
virtual experience I've ever had on the Nürburgring was my first exposure to it on Enthusia...I did a time-attack lap with the E30 M3...all I can say is, E30 M3 + Nürburgring = Automotive Heaven

👍
Aaaaaaaaaaaaaand my vote for the most magical 'Ring experience I've ever had would have to be when I actually drove on the real deal myself.

In an automatic-equipped rental E60 525i wagon, of all things.

I created a thread about it
here.
