My little lad is into car design in a big way (he's only 9 bless him)
He sent a pic to TVR and got a reply from the MD stating that his pics had been put up in the factory for inspiration for the workers. I VERY much doubt this but it made his day. He got a website up the other week and is made up. (a little help from daddy).
His designs are on there - vlick the thumbs. Dont all laugh at once tho http://www.bravo-guide.co.uk/speedyhall
