The floor board rusted after I drove the car for 10 years, year around. when I put the car back together after I rebuilt it the windows did not role down after I put the speakers in.
This car handles great and is a fun car to drive. I love taking rides in it with my 14 year old sun and will one day let him take me for the rides.
The winow problem (not rolling down) is due to the bottom of the windo frame hitting the speaker magnet most likely.
