They are all Locosts really as Uncle Ron's book sparked them all off (me included), all that has happened is the chassis has been tweaked to accept Sierra stuff rather than Escort...... My Lotus 11ish thing was loosely based on Ron's chassis but with a few tweaks, why reinvent the wheel or more to the point claim to have reinvented the wheel...

I can think of at least four firms producing 7's that are the same size as Uncle Ron's Locost a few have grown in size because folk eat too many pies
