You are right, I put on the cost effective estimate. Going on for complete with quality brands will cost around 35-40K.
A client at my mechanics workshop just replaced whole suspension with a new one over his 2006 RXI with a Chinese brand, it costed him under 15K and the car was "really" fine in driving, so I was speaking over this regard.
When my mechanic told me the prices I was kind of astonished also and was telling keh it would not give a good drive in this much amount. But the job went pretty fine and the car is still running pretty fine and noiseless. So if you are short on cash then still LIANA is not a very expensive car to maintain 
I once used Chinese excels CV joints for my previous Cultus, my mechanic suggested me to use them instead of the higher priced ones. I bought the set for Rs 1800, the original ones were costing Rs 5200 at that time. Believe me it worked really fine and is still working as like perfect after more than 1 year (as I sold mine to my office friend sitting back to me).
