I got my 2000 Mercury Cougar from my parents when I was 16. I am now 18 years old and I'll admit there have been a few problems.
1. I was traveling on the highway one day and my car completely stalled on me while I was trying to accelerate on a bridge. Pinned in the middle lane, I managed my way over and rolled down the bridge in the breakdown lane. I noticed I was very very low on gas, and I brought it in to see what was wrong. Apparently the gas pump was faulty and needed to be replaced.
2. The sway bar that turns the wheels had to be replaced once, and tightened twice. I would hear groans when I turned the wheels, and it sounded like something was clicking while I drove. I also felt the clicking in my feet.
3. The next thing that occurred was at night my lights would flash like a strobe light. My alternator was going and needed to be replaced.
4. The speed setting for the heater would only work on the 2 highest settings. Turns out the blower motor which controls that had to be replaced.
Other than those few things, this car is amazing. It is amazingly reliable and handles curves like nothing.
It is pretty decent on gas considering I drive like an ass. And let me tell you, I beat the crap out of that car.
I never have a start up problem, or dashboard lighting problem, and I've never experienced my car dying on left turns, cause like I said, I really beat that car up. My trunk latch never gets stuck.
All in all, I really don't have too many problems at all with this car. It runs great and handles amazingly. It looks nice and is decently fast.
