Hi, I had (may still have) a haynes for the 240... Decent wiring diagrams and paper quality was good (it could stand a bit of greece and oil!).. Got one for the 740 and the paper quality was deplorable, wiring diagrams we next to useless. Cheap and nasty was my impression. They don't do one for the V90, and I wouldn't buy it if they did. Des. . . ;)
