Ah to have a project finished.. If they dont need any work around here they get driven until they do need work. Here is how to placate her, do a project in the house. It can be anything, painting the bathroom, or building a deck. I know it gets a little bit cold in Oklahoma, so an indoor project would be nice.
Once that is done, then buy a two door, rear wheel drive, V8 powered car built before 1980. Make that into a small project at first, easing her into the idea. If its something she likes to ride in, all the better. Turn the car into something you can pull around with your truck.
Build a trailer for it if you can weld.
Alternatively you can come up here and work on my projects, I have enough to keep you busy for a lifetime. Problem is I dont pay very well..
