Insurance brokers for modified cars

[Skeptisk]

I am looking at buying a heavily modified car (rocketeer). Any recommendations for good brokers that specialise in modified or unusual cars?

I’ve used green light and Brentacre before. Not had to claim but both gave good prices.

Greenlight seem decent in terms of customer service IME.

Adrian Flux do not IME.
