I recently acquired a share in a Piper PA-28-140 Cherokee. Any of you
with a lot of hours an experience could give me some hints and tips
about this airplane? Thanks in advance.

Don't spin it.

Why?

Because it probably has both a vacuum driven artificial horizon and a
directional gyro, both rather costly instruments. When you spin the
plane you'll cause the gyros to tumble, which is very hard on the
bearings and other moving parts inside these instruments and will
contribute to their premature failure. For each time you watch an AI or
DG tumble around, picture in your mind the sights and sounds of an old
timey cash register going "ka-ching" "ka-ching" with dollar signs and
numbers in the several hundreds showing in the display.
