Spirit is definitely my LAST choice airline. If I want to get somewhere cheap and quick, I'll check them out. They're pretty hit or miss, half the time I've had no issues and the other half has been a disaster. At least I get to sit in the front of the plane without having to pay my fare times 4.
Love chase. They're really convenient and helpful. I've only had one problem with them and identifying my account. They kept asking me for the branch name and I didn't know it so I had to go in person to do a simple address change. Other than that, I have had no issues and they resolve disputes rather quickly.
I got my first GMC this year. It's a Yukon and I love it. I went to a family owned establishment and the customer service was professional. It took a long time to get my loan accepted and I think I waited there for half a day.
