Friend of mine who owns an upholstery shop goes to Sam's Club - or Walmart, don't remember which - & buys their temporary storage tents for cars & boats sitting outside his shop until he can work on them...he bought me one for my '60 Magnette until I got my garage finished....large enough for that big saloon with plenty of room to walk around & work under/in car....less than $200 & will hold up to high winds, rain, etc.
