Can I leave my rMBP at 15F-25F degree outdoor?

For some odd reasons, I think I have to keep my rMBP in my car. The temperature in my place recently goes around 20F. Does it do any harm to my rMBP?

Thanks.

If your macbook cools down, water will condense inside, corroding the circuits.
It's not the temperature, but the humidity you have to worry about.

I once left an old Asus Laptop in my car and the display broke shortly after that, which might also be caused by low-temperature. LCD are crystals, after all.

Two points to think about.

Thanks heisenberg123 and pmau.

I think the big thing is to let it warm up to operating temp (room temp) before using it after cold storage.
