Not sure if they would quote but Adrian Flux always was very helpful when i was running V8 american sports cars for a time when i was.... a little younger. If sure they would underight you, they insured me on a Z28 Camaro at 23........ I admit it wasnt as expensive as a Morgan.

I tried them again a year ago on a Z1, C6 and it was around £650 fully comp, 7 yrs ncb and 7500 miles.
