Turboomni, thanks for starting this thread. This is a very good topic that I'm sure everyone can benefit from. First, M2C's, I used to start my cars in storage in the winter about once a month to get it up to operating temp and work through the gears. Over the past couple of years, I've heard many opinions that this isn't the best idea because it will likely cause condensation buildup. Best case, only in the exhaust, worst case, in the engine as well.
I no longer start my cars in winter, I've purchased battery tenders and plug the exhaust pipes and wash and detail the cars before covering and putting them away. I've heard horror stories of mice building nests in the mufflers over the winter. I don't know how likely that is but an ounce of prevention.
When I get them out in the spring, I first unplug the tailpipes, check the engine and underneath for any issues, warm them up to operating temp and work through the gears. I then change the oil and take them for a short drive with the radio off and windows down to listen and feel for any issues.
Since I've been doing this, I've not had any problems but don't feel I had any problems related to storage before either so I'm not sure if it makes much difference but this is what I'm comfortable with now.
I would certainly like to hear other opinions and things people do to store their cars. One thing in particular I'm curious about is if anyone has any experience with race ramps. I can't decide if this is bs or something that might be helpful/useful.
