I’ve got a 997.2 in Porsche Racing Green Metallic. The vast majority of them came with full Sand Beige interiors, unfortunately. It’s actually a great color combo, but the entire dash is in tan, and it should be black to cut down on reflections. The carpet, floor mats, steering wheel, shifter, and parking brake are Sand as well, so it’s a bit overwhelming. I just swapped to a 991.2 steering wheel in black along with black floor mats, and it looks 100% better. Next up will be the PDK and parking brake swapped to black as well, and then I’ll be happy. Airbag wasn’t attached yet, but you get the idea:

No Cayenne, get an Audi Q7 or MBZ AMG equivalent No 911, get a GT-R No Cayman, get a BMW M2 No Panamera, get an Audi S7 or RS6 Avant No Taycan, get an Audi e-Tron GT (same platform)

Probably not ‘77, but you’re close; I’m guessing it’s a ‘78-‘82 SC, by the flared rear fenders and black anodized trim.
