Merry Christmas,
My parents bought one of those free standing 10'x20' party tents 3 years ago for their VW Jetta Wagon and works very well!
They paid $125.00 for for it from a patio furniture store.
The only thing they don't use are the side walls with the windows. Why, I don't know!
Jen and I are going out next week and are going to buy one for our driveway. I plan on using the 2 of the 3 walls to add some privacy from the neighbors! Same store has them on sale for like $100.00 right now!
Mai reason we want one is that the neighbors have an apple tree that has branches hanging over our driveway and deposits leaves, apples, and bird shit all over the ground on our side of the fence. That, and the fact that our KJ is to tall to use the garage.
So yes, I highly recommend one.
Cheers
Jennifer & Ryan
