With due respect, i differ from your viewpoint. The prices of the cars are ever increasing these days, how can you expect the depreciation in 2nd hand cars. If in 2012 new GLI is for 20lacs so will you sale your car for less than 9.20 just beacause you bought it in this price and asking price should be low beacause of depreciation?
If there were depreciation in cars then new cars would not have been so expensive. People would have bought 2nd hand cars in low prices. In turn automobile manufacturing company had to lower the car prices in order to increase their sales. I bought my khyber for 322,000 and sold it for 360,ooo. Bought alto 2004 model back in 2005 for 390k, sold it for 445k last month. Do you call this deprectaion? I was looking for margalla last year, the market price then was 370-400k for 96-98 model margallas, but now they are in range of 425-470k. Civic 95 was easily available in 425k but now people are asking 525-600k for their ruined rides.
