The plans were drawn in 1999 before the introduction of UK MSVA (Motorcycle
Single Vehicle Approval) regulations and therefore UK builders with the
intention of registering their car for use on the public highway are advised to
familiarise themselves with the MSVA regulations and build their car
accordingly. We know of at least three (there were probably many more that
never told us) plan built cars which passed the UK MSVA test and were successfully registered for road use.
Some changes to the plans may be required to satisfy the requirements of the MSVA
test. The MSVA guide is available from VOSA (Vehicle & Operator Services Agency) for just £30. Click here for details.
