Rear shock absorbers are a pain in the back

The car is overall good, but it hurts that they reduced the price after I bought my Honda City in Diwali last year. even more disturbing is its performance on the Mumbai roads.

I commute in my City from Thane to BKC everyday and everyday its a fatigue event for me, Especially since the road conditions are not getting any better, it feels almost as if I have got off an air conditioned autorickshaw. 

Have checked with my service dealer Hallmark Honda, they say nothing can be done as it is a 'semi-sports' car design and has issues in the suspension. there is definitely something wrong as I have travelled in this car in its earlier version (the dolphin one), it did not have this issue. Its come up in the new Arrow design, where everything seems to have improved but the suspension has actually deteriorated.  Really not expected from a car that sells in the 10 lakh segment. Am looking for a way out as I cannot sell the car, nor can I get used to the bumpy ride. If anyone has a solution, pl let me know at amol_md@yahoo.com, really appreciate it.
