Not something I'm proud of but couldn't resist. Were given brand new Porsche Cayennes to take out to the desert camp. That time the Bawadi road was a good straight 30 kms with out any R/A's or flyovers and no one even knew it was there.
After a while at 240 realised it probably wasn't the best thing to do so slowed down. The longest I've driven is around 1200 kms maybe even more. Been a couple of occasions where I jumped on the seat 8.00 am and got off 8.00 am the next day with very few and short breaks. Something I do not wish to ever repeat again though.
