bikerbob 100 Bob Fit and finish on 98% of ERA cars are perfect, like the paint jobs. The only issues you will have are the drive train. You can have someone drive it, check it and still not be 100% sure of not having a problem. If this is an FE motor in the car, 90% have a small leak of
oil. For checking the motor, a compression test, leak down test, and pulling rocker covers to look at rocker are about the most you can do.
Other things to check,
road test, shifting of the trans
clutch, how it feels, is it new , replaced or OEM when the car was built
rearend. heck the other hubs for end play to the wheels
greasing of universal joints.
Rearend should be quiet, do a short burnt out in water to see if the posi is working ok and not just 1 wheel spinning.
Check front end ball joints wheel bearing.
Most owners of ERA are Honest and straight about their cars. Call ERA with the build number on the car and you should be able to follow the family history back to ERA. The car is probable fine. Good luck Rick L.
