Just seen some lotus 7 chassis proper engineering diagrams on ebay. The highest bids £16 and theres about 22 minutes left, so hurry if you're interseted

These are back on ebay. Do you reckon they'd be any use in building a locost?

could well be helpful, but the seven that the locost is a replica of is the series 3 i believe, i dont know what the diferences are tho, could be minimal.
