The fun police will stuff it up in the end they allways do.

90 days a year would be more than enough for most drivers I would think. I bet ther would be a lot of fully registered cars that get driven a lot less.

Here's another thought.

Ship your car to the UK $3,000 as a race car register under SVC to get UK rego say about another $1,000 and then bring the car back as a personal import $3,000.

Then just run it over the pits to check lights and wipers etc and get your local state rego.

The UK are fairly fussy but nowhere near as much as here.
They can still run carbies and live side pipes so that shows you how fussy they are.
