$2480 isn't all that bad when you realize that they are charging you north of $1600 just for the alternator.
It is a lot of money, when you can get one from Autozone for +/- $180 and X/O yourself in less than an hour.
I had a dealer quote me +/- $600 to replace my passenger side mirror that stopped working. Turned out it was just unplugged. I pulled the trim piece off and plugged it back together in less than 10 minutes. Problem solved, money saved. Cue the perma-grin
Look for the local PCA chapter and make some new friends. They could/can be a huge resource for you going forward, i.e. trusted indy mechanics, private sellers, etc.
