No you can't rent garages it is highly illegal!!!If the feds catch you you could recieve 20yrs inprisonment,evan the death penalty in some states and provences.And if your caught in one of those car storage crime rings you could be shot on site by a US marshall.As a matter of fact you could be fined up to $25,000 by the EPA for storing your car in a rented garage.Local authorites can evan allow the K9 unit to hump your leg without reading you your rights first.
Or you can do like me and rent a stall in a U-haul unit for $85 a mo.includes lights bring your own lock.
