First question - what is meant by 'bad serpentine drive belt'? If the belt is completely broken in two - then no, the vehicle cannot be driven.
If the belt merely shows signs of wear - such as sections of the ribs missing - then you can drive, but have a new spare belt on-hand to replace. If the belt is replaced, be sure to also replace the belt tensioner at the same time.
Try these online resources; www.autopartswarehouse.com, www.rockauto.com, www.partsgeek.com - to list only a few.
In fact, they (RockAuto) list the replacement serpentine drive belt from around $5.00, and the belt tensioner from around $27.00 for your vehicle.
