New/old motor for the duster

Rent a storage building, I had to for more room. I have my Willys and Duster in one.
Its kinda expensive, but keeps the vehicles out of the weather, and the wife *****'n crap is in the yard.
I did already... my truck is in storage this month to give room to switch everything out with the duster... $200 a month= $2400 a year+1600 or so a year for insurance... (For the truck 25k agreed, duster 15k, and ta 9k)
I drove the duster 4 times last year... Once to storage once back home (+6 mouths storage fee $1200) and twice around the neighborhood to keep the tires round...
I just don't have time for it and I want to do other things with the money than pay storage...
My wife never complains about any of my toys...
