AOA I have encountered many ppl saying suzuki swift is a very good car I personally like swift but when a some person say suzuki liana being a bad car even after share same engine,axle,suspention,brake in short every physical performance part and say that suzuki liana have swift use same engine but different head so I visit shershah to physically inspect engine as suzuki swift and liana have different plastic cover/airfilter cover it was easy to differenciate between them I inspected some head of swift and liana both were exactly the same then I told the whole to a shop owner and then the shop owner told me full story he told be there no difference in both infact some imported suzuki aerios engine have a different plastic cover/airfilter cover and it just a plastic cover/airfilter cover difference in both engine so I researched on internet and found the shop owner was right I am attaching a pic of suzuki aerio engine bay for reference
