I'm not sure if it matters, but the car was built later in the 1989 model year, it's got that 25th anniversary deal on the dash, so I'm not 100% sure what color is right ?If I had to guess I would say the Medium Grey....I guessThe info I have shows the following for interior grey colors:
1984-1986 Charcoal Grey
1987-1989 Medium Grey
1990-1992 Titanium Grey
1993 Opal Grey
