>>284811022013 Dodge Dart, tore out all interior plastics rear seats and the carpet. I was not happy with the leg position and to get the carpet out to foamectomy it you have to take all the rest of the interior apart too. ended up just leaving it because the bright red paint was nice, but you end up with lots of sharp edges so i put the front door cards and center console back in. also surprisingly big mpg improvement without like 150+ lbs of interior crap. the road noise didn't bother me so much. car sounded good too.
having no headliner was a real killer in summer and no carpet and thus no floor insulation sucked in winter. then some electrical shit happened with the HVAC control cluster that made the a/c inop so i traded the car for a miat which was somehow quieter.
