Mark has been selling GT40 parts on Ebay for quite a while now - bellhousings, flywheels etc. Maybe the selling of chassis is an extension of this or a step towards a new company. As the ad says this is an mda chassis but whether this is an old one or a freshly made one we don't know. The chassis is a good one and does handle well. I have ridden in Steve Barker's mda and it is a really nice handling car. Mark Hales also liked it's handling when he drove it at Goodwood.
