This is my first lexus and I am used to buying chilton or haynes books for my used cars. I just bought a 91 ls 400 and can't find one by them. Baffling me. I also haven't been able to find any used service manuals. Don't understand why its so difficult to find decently priced manuals for such an old car. Can anyone help as I prefer to do as much repair work myself as possible as I am very budget minded..lol.
