Home made pick ups and MOT/IVA

Changing the subject a bit, I understand why chopping a section out of your car to create a pick up would require an IVA, but what about adding to your car? For instance creating an estate car from a saloon car?

That's what I figured, so it would still need an IVA, and get an ageless 'Q' registration.

Definitely a Q-plate, if the shell or chassis is cut as part of the modification but everything else stays original or using other s/h parts, it falls into the Radically Altered Vehicle category.

The only way you can gain an age-related plate is with Kit-Converted or Rebuilt Vehicles.

Rebuilt vehicles must use the original unaltered shell/chassis.

Kit-converted can be a modified shell/chassis, but must have a new 'kit' of parts built into it from an Kit manufacturer.

It's a proper minefield to get your head around for sure.
