I have had a lancer since 2006, its driven 115000 kms till now with no issues and just has had periodic maintenance such as oil, filters, brake pads changed. The drive and the comfort is far superior than a corolla.
Bodyparts are slightly expensive then toyota but they are available in market. Regular maintenance parts are available everywhere and at similar rate as toyota and honda.
The mileage is slightly on the lower side, i get around 8-9km/liter with ac within city.
