OK... quick question with more answers than there are worms in a can...
The insurance will require an engineer's report on the modified vehicle I propose to build.
The insurance agents have a flat rule not to be helpful in the matter of modified vehicles (I get on well with them normally, so I think this is just "rules") - they're not supposed to help in any way and that includes supplying information about engineers.
So... anyone done this recently, and if so, who did your inspection and how were they qualified?
I've been told (and perhaps this was a hint) that other people have used MOT inspectors and not had problems. But I don't want to commit time and money to the project and then have them say "oh, well, this chap is no use, you need to get it inspected by $XYZ"
Furthermore, ideally I want to run the plan past the person who'll be doing the inspection before starting work so as not to fall foul of any silly errors which will be easy to avoid and more difficult to correct after the event.
Of course, if any of you lot are qualified to do vehicle inspections, I'll willingly pay your expenses and buy you a beer to come and look at it :-)
