I've used the long term carpark many times and never had a problem. I worry more about weather damage (hail, etc) as the carpark is not undercover.
They offer a valet service now which saves the hassle of waiting for the dreaded shuttle bus with all of your luggage. If you're gone for more than 7 days, it's not much more than parking the car yourself.
Another option is staying at one of the airport hotels the night before you leave, and getting a package that includes parking. The Stamford has undercover parking.
