Do, however, pump the brakes at least once a month to keep the caliper piston seals flexed. I also roll mine forward or back once a month to prevent only one flat spot on my tires

I heard the same thing, unless you're going to drive it a bit there doesn't seem to be any benefit to it.

Mine stays locked up for the same period of time, when I start it up in late March or early spring, I let it warm up and take it slow for the next 20 miles or so. Then I change the fluids.

 

 

I agree, BUT, you really should drive it to warm it up. If you start a cold system and let it idle until it warms up, you can do significant damage to the cat converter because it does not get hot enough fast enough to do it's job efficiently and can start to clog (see GM's warmup recommendations in the factory service manuals where it discusses similar idling when servicing the AC). Also, a lot of moisture collects in the exhaust system that doesn't really get blown out or dried up by running in the driveway. Our problem here in the north is we can't (won't) take our cars out on the salty, slushy roads and warm them properly. Therefore, in our cases, it's better to leave them alone. A few months of unuse indoors isn't going to do any harm. Keep the brakes flexed and the mice out. Roll em forward one month, and back the next to avoid flat spots. Get a good battery maintainer. Pray for an early spring
