Unfortunately the maintenance of Alto 660cc is very expensive as compared to old Suzuki vehicles like Mehran, and old Cultus. Actually, all the new Suzuki vehicles are no more cheap to maintain.
Look at the part prices of new Swift. 5398 for air filter and 2567 for oil filter. Seriously?
Honda City looks cheaper to maintain after looking at this table. Also, the fuel saving benefits that we get from Alto is lost in parts.
Another interesting finding is Alsvin parts are even more expensive than big 3. I found this when comparing the B-Segment sedans before purchasing City. Couple months back I compared the brand-new transmission prices of Alsvin DCT (12 lacs) and Honda CVT (7 lacs) from dealership. Similarly, the price difference is there even for everyday parts like oil/air filter.
Unfortunately, all newcomers are even bigger thieves than the old ones. Most of them are using this strategy. Sell vehicle at slightly less price than big 3, but loot the customer in parts and after sale services. In the long term, they are earning more than big 3.
