Apparently my upholstery skills are similar to Jay's. When I took my headliner out to be recovered(3 months ago), I discovered that I like running without. The only reason that I will put the headliner back in is to recover use of my dome light, I miss it trying to read maps.
An associated topic: How expensive are the plastic trim pieces that surround the headliner? I've saved most of my pieces, but the headliner/windshield trim will take some creative repairs.
Thanks,
Mel
