How to prep my M3 for proper long-term storage?

Same here, I was using a public storage unit to store my M3 due to lack of appropriate garage until recently. No dryer sheets but the facility seemed to have rodents well under control. Used a 10’x20’ outdoor access storage unit, so not an actual garage, but the staff helped me pick a unit I could pull the car into and had no problem with me storing a car that way. There was a tiny bit of room at the end to store some other odds and ends too, which was convenient.

I’d swing by every 2-3 weeks to drive the car around if possible, and ended up keeping the car in storage from November until March with battery being maintained at home and fuel stabilizer while the car was parked. The only item I didn’t anticipate after reconnecting the battery was having to drive the car enough to get it ready for emissions test and spring state inspection (inspection was expired and of course I got a ticket for it while trying to drive it enough for emissions test). Otherwise, the car just got very, very dusty!

I used to rent a garage at one of those public storage units and it was fairly simple. I live in Florida so the biggest thing was keeping rodents and moisture out of the garage.

I recommend placing dryer sheets all around the car. The scent keeps mice and other critters away from your wiring and engine bay. Outside of that I had no real problems, besides getting super dusty. The car would sit for 3-4 weeks at a time and I would go start it and drive it around the block for a few.

Since you’ll be able to get to the car once a month or so, I wouldn’t worry about too much else.

New housing arrangements for me means I have to park the M in a locked garage uptown for the time being, and will likely have to get a daily driver to keep parked on the streets. It will be parked in a locked garage spot, however it's not climate controlled. What are some things I should do prior to storage to make sure the car stays in the tip-top shape that it's currently in? For reference, it's a weekend car now but that will likely be relegated to monthly-weekend car. I'll be able to check up on it at least once a month to start it, warm it up, get the fluids circulating, roll it around, and make sure the battery keeps a charge.

Anything in particular I should keep an eye on/prepare for as well? I've already got a towel covering the dash in the event the rearview springs a leak.

Thanks!
