Interior wasn't THAT awful. I thought it complimented the car well enough.
Doesnt seem it would be all that hard to revert to OEM. I did not pay attention to what it was from factory
Unless all the leather parts come with the car, I don't think you will be able to take it back to full OEM....my Ford GT is like that, looks great with contrasting stitching matching the exterior color and the leather itself is miles above what Ford used, but I don't think Ford is selling replacement seat covers any more.
Gotcha; I had figured it was just a matter of reupholstering them with a good leather shop back to the original style.
