Given how hard it is to find a two-seater top the price is not bad though it will definitely need a full restoration.
Years ago I bought a top for my ex-wife's BN7 that was owned by a fellow who had a beautifully restored BN6. He sold the car to someone who simply did not want the top and I bought it for $2200.00. I drove her car up to the Harrisburg PA area, paid for the top, clamped it down and drove home.
The top was a fair fit with some significant gaps along the rear deck and it needed new windlacing and gaskets. I figured that new rubber would make up the difference but no matter what I did and how hard I applied the clamps the gaps would not disappear. I am of the belief that even though Healeys were production cars there was enough variation from car to car to require custom fitting and when tops were fitted to cars at the factory they likely had the benefit of having several on hand to choose from and picked the one that fit the best before doing final trimming, etc.
I always intended to do a complete rebuild of the hardtop but we got divorced before I got around to it. I miss that car.
