Two month ago i visited the Ring.
This was my second time.
I did 11 laps with Rent4Ring's BMW 125i.
I would do this again and again.
Too bad it's quite expensive - those 11 laps costed me ~1,000 eur all included.
Renting a Porsche there is out of question unfortunately because it's very very expensive - for example RSR asks 2,200 eur for 10 laps in Cayman S and 3,000 eur for 991 gt3
