Took my 2012 Lincoln MKZ with over 110k miles on it to have the air conditioner looked at since it was no longer cooling. I didn't want to take to dealer as I knew I would be overcharged for an older car. Turns out it was only a temperature sensor that needed to be replaced. Not a cheap repair but reading what it takes to correct the problem, I thought it was very fair. The guys there were really nice too and did not try to upsell me on anything.
