[Resolved]  Maruti Suzuki — Alto 1.1 resale problem

I bought Alto VX in Jan 2001.Company has launched Alto 1100cc in VX model in 2000-01 after one year it has stoped its production at that time its price was 3.80 lakh . after one year company has launced Alto Lx 800cc engine in same chasie no change externally at cost 2.25 lakh. common man do not believe that both cars are different . My cars resale price is going to decide on the basis of new price of Alto 800 that is not genuine . It is due to companay . because they about own profit not for customers.
Please give me appropriate advise
