Hey Ashmole,
Well, i have only had the chance to drive and be driven in a deisel scorpio on a good metalled road. I literally felt sick in the back(middle) row of seats. The suspension was just way too hard and i was hitting my head on the smallest of bumps on the road. Maybe the car wasnt loaded to its capacity (had only 4 people in it), maybe the tire pressure was too high, and maybe this has been sorted out by mahindra on newer models (because this was when it had just been launched).
cya
