Since October of last year I've done four. They are all survivors and have been taken down, overhauled with consumables being replaced as needed. None of them are restorations or anything worth painting. I do it because it gives me something constructive to do and I enjoy the results.
Some day I hope to find something classic or collectible and make a long term project taking my time to do a meticulous restoration. But for the time being, I'm happy just wrenching on them and riding them.
