OMG- Now after reading this I couldn't believe it and I am a woman

- I would NEVER tell my husband to trade any of our Camaros for a KIA!! That is the most ridiculous thing- of course you were very kind telling her to fly a kite my husband would divorce me!!!
I know have your wife test drive your Camaro and then take her out to drive the KIA right after- NO COMPARISON!! Do you let your wife drive your Camaro???? If she drives it and she still says this someone else was right she is around the pixie dust too long!!
Now...if you don't let her drive your Camaro...she might be resentful and this is why she would think the KIA might be ok. Either way, if you had to trade in your car you should still go American dude- get a Malibu at least will last you longer with less hassle.
