as a definitive answer, the long and short of it is an IVA is required - period!
i know the test is expensive, but its a legal loop we all have to jump thru that ensures its suitable for use on the road. the test is different from an MoT (yet similar) where they look at how the car was contructed (not the case in MoT's), checking speedo calibrations, checking its properly assembled (non-structural) etc. also from an insurance/police point of view, should you have to make a claim you're likely to have a hard time prooving its still a mx5 (engine are easily swapped out so aren't proof).
lastly, in respect to the sand rail & beetle - the chassis is unmodified [classed as a platform/structure which the drivetrain and suspension/axles are fixed to] thus retains its original identity (incl. VIN) provided the log etc. is updated to reflect the change (i.e. "body" change).
the mx5 however, the sub frames cannot be classed as the chassis - while they do form a platform for the suspension and drivetrain they not structural to the whole vehicle as they not linked as one component hence they not classed as a chassis. the PPF merely links the drivetrain which is seperate to the sub frames.
the mx5 chassis is integral to the body and cannot be seperated thus the identity (& VIN) goes with it. all this is pointed out in the DVLA rules regarding registering a vehicle and wether an IVA is required. the original SVA was introduced in 1998 to prevent vehicles being incorrectly registered in this way - as a consequence it forced the then and often shoddily thrown together jobbies off the road (sometimes the kits rather than the builders!)
so there it is, the IVA is required. but its not hard to overcome, a little common sense goes a long way - if something seems loose or flapping, perhaps an extra clip or bracket etc... or that bolt/bracket/clamp that juts out and catches your [insert choice of limb] could be better positioned...
hope that clarified things a little
