I wish I could afford to get him something like that!
I custom painted one of my other friends wheel chair years ago. It was a fade job from purple to yellow to red candies. He used it for years and retired it. His new chair ended up to be too heavy for him to get into his car so I went and got his old one that I painted it was a little Quickie like this one.
And I stripped all the paint off it and polished it and leaving it in bare aluminum, it looked pretty cool. He is a WWII war bird nut so he digs it.
