Mark Ive put a cat B flood damaged defender back on the road.

No need for SVA/IVA. Was VIC checked as DVLA required a VIC check when i changed address on the V5. Ran it legally for a couple of years before selling on. Insurance even paid out minus salvage charges. They didnt like it though but as its legally my vehicle at the time they couldnt stop me. Sure it was 10 years ago but the code of practice has only been updated since then, not fundamentally changed.
Where is this legislation on cat B's being SVA'd? You dont loose the registration plate either, mine didnt.
Perhaps you should read the VOSA/DVLA site and the ABI code of practice. Nothing says its illegal to put cat B (or cat A for that matter) vehicles back on the road.
The entire ABI code only applies to those signed upto it, and not private individuals.
There have been threads on here before about people perfectly legally putting cat b's back on the road so its nothing new or special.
