No, not much. I have driven it extensively in Ghat sections at good speed. My family members have stopped taking motion sickness pills after we bought the Avventura. This is also resolved forever due to new improved lock & the mechanism, In my case they have replaced the lock, the mechanism responsible for rattling, all under warranty, they haven't charged me a single paisa. @Joe_Gunner, if possibility of sabotage is low if parked outside, go for Avventura. If the road surface & it's routine maintenance (of the road) is good or bad, go for Evo. If the road surface conditions are bad to worst, go for Avventura. Anyways, do you like to slow down too much on the speed breakers? And approximately how many speed breakers are there on your route?
