I have two that dont even have seat belts, never did. I do plan to upgrade to some just because they are proven, and I am more concerned about my little girl than anything else. but Im not gonna lose any sleep over it,nor quit driving them just because they arent in there. There arent any turn signals or brake lights for that matter, which goes with the safety standards Vile mentioned. Lots of things have changed and are changing every year. Fix what concerns you, and enjoy the rest. I dont think I need to install tire pressure monitors on my 51, like the newer ones have, but the seat belt isnt necassarily a bad thing. Just my opinion
