$76 an hour for a 1980 172
$35 an hour for instruction

But, that is out in Colorado.

Back home in California,

$99 an hour for a 1980 172
$50 an hour for instruction (low end is about 45, high end is 55/60, up to 75)

Cheapest I have EVER seen was a 152 at $40.25 tach. Of course there was a $100 joining fee and a $40 a month membership fee, but $40 an hour tach is pretty cheap!
