Yes definately make sure you start it every now and then. Once a week or so will keep you gaskets from drying out and keepin your battery charged. Letting a car sit for an extended period amount of time is extremely bad for the car. Actually you should let someone drive it honestly. That way you keep most of the moisture out of the exhaust and you keep the tires from going flat. Even if you can't find someone to drive I'm sure you could just take it up and down the driveway.
