I'm sorry if this doesn't belong here, but when you said your son folded himself into the car I just have to tell this story. When I was a kid (a long time ago), my uncle built a little car that closely resembles the one you are working on, and he powered it with a 3 hp briggs and stratton gas engine. When he got it done, he asked me to come and test drive it before presenting it to his grandson for his birthday. When I arrived, he explained the controls to me, and I hopped on. I could barely squeeze my legs inside this thing, but I wasn't going to let that stop me from a maiden voyage. I roared off down the sidewalk, made a big turn and headed back. As I approached the driveway, I realized that in my cramped quarters I was unable to push on the brake I narrowly missed my uncle and plowed into the back bumper of his car. I think that was the first time I have ever seen a grown man cry - and then I thought he was going to kill me! When he finally settled down, he took the little car and eventually straightened it out fairly well, but it never was pristine again.
