Do a search, lancelot. Virtues of owning a hybrid and non-hybrid has been discussed to death here.
My 2 cents:
There is no point in buying a hybrid if you're travelling only 36Kms under less amount of traffic; you won't save much on fuel. And if the hybrid battery start acting up within 5 years, you will be left with a loss; even if it didn't, hybrids are NOT known for holding their resale value.
Lancer EX is a trusted workhorse and relatively not complicated; so it won't be a trouble maker. Plus, all the Lancer EXes here in SL are Brand-new imports and there is a specified agent for the brand. All the Lancer EX owners I know does their periodic maintenance at the agent.
Lancer EX will do 10-14 Kms per litre; that's the norm for any 1.6 petrol engine. If you drive in less traffic-y roads maintaining a 10+kmpl FE wouldn't be hard; however FE depends on your driving style.
With those two enormous red round tail lights and misshaped rear, aqua looks like its gang-banged and a$$-raped by aliens with huge D's. Lancer on the other hand, is in a league of its own when it comes to design and sex appeal. eye of the beholder tho.
Driving pleasure wise, aqua cannot hold a candle to lancer. I've driven both cars. Aqua's GC is not meant for SL road conditions.
As I said before search the forum; there's a butt-load of info on both cars. Lancer EX is discussed extensively at the BRATT thread. Google "BRATT autolanka" you'll find it. Search "Site:forum.autolanka.com aqua / Site:forum.autolanka.com Prius C" (I cannot find watchman's thread so typed it myself - not feeling sleepy yet )
I wish you luck on your car hunt!
