Scotty, my Fiance has a 2012 Honda Civic, the "check emissions system" light just came on. What can I do myself to treat this problem before going to a mechanic? When I drive it myself I can smell exhaust outside the car but nothing inside.
Also, I will soon be purchasing a 2005 Chevy Malibu from my parents. What are your thoughts on those cars?
Clarification: You should post these as separate question threads to get more (and complete) answers. If you scan the vehicle at the ODBII port for codes, what comes up? Please post them here.
Regarding the 2005 Chevrolet Malibu, I would pass. See below:

Check for codes on the Civic. If you really want a Malibu one of these would be a better bet:
beeeeutiful!
Start by scanning the Civic for codes.
Is the exhaust sounding unusually loud? If yes, check for exhaust leaks using smoke.
Also, politely pass on that Malibu..
