Kits parts direct was Lolocost which was owned by Richard Stuart/Robin Hood Engineering before being sold to GBS.
Lolocost started selling Locost parts and added Robin Hood parts later on.
They sold both Robin Hood sized parts and Ron Champions Build a Sportscar for £250 parts including a chassis.
Currently they sell a mix of Robin Hood and Locost stuff.
Most of the stuff is OK but pays your money etc.
You can see the parts on the GBS/Robin Hood stand at the shows.
But like everything you should check price and quality and compare.
