I got round to showing the picture to my 17 year and he was impressed and asked how much he'd done himself. If yours is anything like mine I'd guess dad did most of the work.
TBH while I've set him well on the road to being a total car nut he's very much got his own ideas on exactly what he wants so its all down to him in terms of ideas and contacts etc but yes it takes a certain amount of discipline from me..............oh and money
