The lower section of my car is dark (charcoal & black except seats), the top 1/2 is beige/tqn (whatever you want to call it) as it was originally light grey (so this colour is actually darker than what i had). And as i got the burnt orange 350z seats for a steal ($250 - good luck finding a set at this price) i actually dont mind the colour so trying to match to them.
As you can see the lower is darker and for a car that wits in the garage 90% of the time doesnt get kiddy grime.
As with all cars they are for individuals and your post is appreciated. Beige interior os so much better than the light grey thats for sure. Oh and i am 1 of 2 m35s (that i am aware of ) who have the rear roof panel not molested by 3 child restraints.
