i think Bala is overcharged. i have seen this many times. when an estimate/bill for insurance company is prepared its hell lot of overcharging. but when they charge to customer they charge very less. i suggest you put the scanned copy of your bill on the forum. after most of the members review it we will pass it on to FIAT demanding explanation / corrective action against your dealer. there is a standard chart for labor and parts charges. sorry to say - Innova person was a dumb. he should have screwed your driver and taken all repair charges. might be his car was out of insurance/ not valid permit or something. there is a golden rule - you need to keep distance keeping in mind ability of your car and your driving and keep enough distance to cope up with someone in front of your slams brake for whatever the reason may be. always the person banging from behind is at fault. a person in front car stop for many reasons.. may be to save someone etc.
