Know several guys that have removed the sunroof by having a panel welded in, painting and new headliner. But then the car no longer matches the build sheet.
This car recently came up for sale. It's a 94 GTS with similar miles to mine, but has been customed out. It has 996 seats, storage instead of rear seats, sunroof delete, painted a custom non-porsche color, rear GTS reflector removed, etc. Listed for $58K, and no-one has snatched it up yet. There is another Gray GTS with a lot of interior and similar exterior mods as this car, that has been languising for a year and he recently refused a $26K offer. Both of these cars people say the 996 front seats is a real turn off.
