But I do agree, Lancer CS3 loses to N17 when it comes to resale value. But If you want Comfort and Driving pleasure, go for the Mitsubishi. And UN*MO's ASS is wonderful (but a little costly but when compared to most other agents of popular brands i.e. Honda (sta**ord) they are less expensive.) So to sum it up:
Driving Pleasure : Lancer > N17
Power : N17 1300CC is wayyy underpowered
Comfort : somewhat similar
Cost : Similar
Looks : Beauty is in the eye of the beholder - But for me it's Lancer
Resale Value : N17 > lancer
This is my opinion only - At the end of the day it's your choice.
Good luck with your car hunt!
