How long can I let my car sit?

As fall and winter approach I will not be driving my car (08 E60 M5) as much and I was wondering how long I could let it sit without driving it? My main concern would be damage or something of the like that could occur if I let it sit. Should I start it up once a week? Once a month? It prolly will not sit unused for more than 3-4 months at a time. Any thoughts?

get a battery tender and you should be fine

if weather permits, it wouldn't hurt to take it out now and then in the winter just to get the car fluids circulating, and preventing the tires from flattening/dry rot. Otherwise, just ensure your tires are properly inflated.

Try to drive it or start it up atleast once a week.

Its good for the engine and all fluids.

Agree, howeverI would say once every week or two. BUT, only do so if you can drive it for 15 - 20 mintues to get to full operating temperature. If that's not possible, it is better to put it on a battery tender for the winter and leave it. I would not recommend just starting the car and letting it idle for a minute or two.

if you just fill the tires up properly and just let it sit over the winter it will be perfectly fine. remember I know it is not a ferrari but there are a TON of cars that sit for much longer then a half a year and never get started and they are just fine...just start it up once a month. Let it warm up for like 5 min, its bad if you just start and stop your motor cold. My M5 was sitting all its life until last november, had fuel stabilizer in it (thank god) but it was also never seeing less then 67 degrees in the garage. I got a '06 with 1,132 miles on it! took it to BMW replaced all the fluids after sitting all its life and the car is a total animal. Only have 7k on it and it drives like I took it off the lot.

bottom line
-fuel preservation (griots sell its)
-proper tire inflation
-battary tender
- car cover or a nice place to sit.

Looks like I am going to grab a battery tender.

I am also planning on keeping it full of gas, I always heard it was bad to leave a car in below freezing temps with empty or close to empty tanks.

you need fuel stabilizer... and all you need is a solid 1/4 tank... you dont want a full tank of gas that has fuel stabilizer in it. when you go to drive it you'll have a whole tank of mixed gas..... and if it is going to stay out side or just get near elements, get a car cover. shumacker or how ever you spell it, has great battary tenders
