I store my antique car in a bank of garages on Spring Hill Terrace in Somerville. The property is owned by a nice old guy:
Ralph B. Frongillo
52 Fountain Street
Medford, MA 02155
I don't know his phone number, but you could write him a letter and see if he has any garages open (there are like 20 of them on his property).
Hope that helps.
