Walmart had a Coleman Max chair for $20 these are great and fit even the biggest of our friends.
Firmer seat than a traditional chair
Extra wide with slanted back
400-lb. weight capacity
We just purchase an 09 Honda FIT with automatic transmission to tow. Although you said used the price was lower and the owner manual clearly states what you need to do. It also is ligher weight and I am hoping that will help gas milage.
