Thanks,
The "Ain't no chick car as I like to say!" is a good description of
the steering for my Cos. Had some decent weather and a chance last
week and run her on a challenging road, I don't think I have a
problem. Really wouldn't want any softer steering. It does turn 4.4
lock to lock and am running 60R-13 tires. Now that I think about it
my old mans 69 Malibu, that I learned to drive on, with no power
steering, was this challenging too. I guess I have been spoiled by
all those cars with power steering.
Dave
