I have a blue 1988 Spider Quadrifoglio. The seat covers and foam are SHOT so I definitely need to reupholster. I'm not personally a fan of the grey leather and red carpets. If it were a blank slate, I'd reupholster in tan leather and black carpet. How "sacred" is sticking to the original color choices in terms of value? I'm not that in tune with the market, so I'm worried if non-original seats will be an issue if/when it comes time to sell it.
