He is a very thorough mechanic who restores old cars and also adds performance parts to muscle cars. |

Dan is used to doing performance cars/upgrades, so he probably got the best bushings he could get, performance wise, and "upgraded" the suspension for handling and not ride comfort. Even though this car is not a "Mark Donohue" flying brick, it does handle great, it just rides like a buckboard. I am going to sell it and get something that rides more smoothly. |

I agree that the nylon bushings are apt to be a lot of the issue, but by the same token I bet they improve the steering feel as well. And the tires may not be blameless either, it is probably a combination of factors. The Matador... and other AMC cars of that era... are not exactly known for gentle rides and tight handling. You are probably getting closer to the original handling qualities of the vehicle. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I remember driving a 75/76 Matador at an AMC dealer, and it rode a lot smoother. I think that having the "Go" package on this car has a lot to do with it. I also think that the radials are making it ride hard as a cob. The steering feel is just as numb as the "full-time" power steering of all the old Chrysler products. I have to keep my eye on the road constantly or this thing wanders off, I can't even feel the tires on the road. |

You're pretty much stuck with the ride. Your new suspension is doing what it's supposed to do. Adding bias ply tires will probably cause your dentures to fly out of your mouth like bats out of a cave in the evening. I suspect that your vintage is too old for a car of this vintage. |

Hell, I'm only 61! I bought a brand new Hornet in 1974, and it rode a lot better than this Matador. BTW, I don't have dentures, yet! |

It would bounce a little sideways. I dug the handling and tolerated the ride. At least it didn't have the numb-nuts steering of the American cars. These cars had a faulty trunk seal that would cause exhaust gases to get sucked into the interior. My eyes would be actually watering sometimes because it was burning a little oil. Boy those days were a gas - literally! |

It was a cute little car. Better than that Opel that looked like a shrunken Corvette! |

And this, in short, is why the Japanese car industry totally clobbered us. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
