Welcome to our Canadian friends<ul><li><a href="http://webpages.charter.net/parkhill/R8/R8_VIN_List.htm">R8 Registry</a></li></ul>

what is option (PBS)

If so, I do not know with any degree of certainty. GBS is listed on a car with an Audi Exclusive interior so it may be related to that.

If you meant PBS, give me the car number and I will look for it but it is probably a typo on my part.

I've seen a few early cars with 7N0002xx numbers on them. Pre-production??
