Welcome to the Forum. I've copied a post I did on Z3 M Coupe Forum when someone asked about classic car insurance.
"As already mention it's nigh on impossible to recommend a particular insurer as things are so different for each company - ie agreed value, mileage, dashcams, modifications etc.
However I can give a list of companies I've used over the last 15years.
Elephant x 3 years
Adrian Flux x 3 years
Saga x 2 years
Brentarce x 4 years
Manning x 2 years
Adrian Flux x 2 years (current insurance - £240 + £15 for agreed BMWCC value)
I've also tried Classic Line, Footman James & BMWCC Insurance to get comparisons at various times.
Hope this helps."
As already mentioned above sometimes even mainstream companies can give you a good quote, maybe as an introduction offer.
All you can do is get busy ringing up for quotes.
