And you won't have to do it alone. This is not another 'how to' book,...This is a phenomenon! Like the orginal Lotus 'Seven' by Colin Chapman, on which it's based, interest in Ron Champions Locost 'Seven' has vastly exceeded it's creator's expectations and attracted a world-wide following of builders, planners, drivers and dreamers. So what does the book tell us? Everything we need to know to build a very desirable ('very', in this context, is supreme understatement) road-registered sports/racing car in the UK. Since the first edition of BYOSC, clubs, race teams, 'E'groups and individual websites have formed, all sharing experiences, helping source parts, find answers to builders' questions, and, for builders elsewhere, advise on variations or plan modifications required to comply with design regulations wherever you decide you've gotta have one. This co-operative system is well supported by the second edition book, which list's organisations, books, and specialists who can provide project support. It has been particularly helpful where different market conditions, environmental or legal requirements make sourcing of donor vehicles and parts as specified in 'the book' somewhat difficult. For instance, as a frustrated Aussie builder, I was referred to "E-groups-Locost" where fellow enthusiasts told me how to re-spec'with GM Holden and Toyota bits, so I'm now powering my first chassis with a Toyota 4A-GE 1600cc,DOHC,16valve,fuel injected 'V8killer'. There will be other performance enhancing modifications too, all made possible by the research and development of the support network, and the fact that Mr. Champions masterly design is capable of absorbing considerable 'tweaking'. (wait till the $40000+ Lotus/Caterham bunch see this one! )..... Probably the most glaring omission from this book is a warning of the addictive effect of reading it! Go on, read it anyway,...your build-project will add to the statistics that will help me justify my project to 'herself' when she realises that the steel tubing delivered last month is not going to be the new pergola she expected.
