Sorry, I forgot to get this information for you. Here are the paint & interior color codes for my truck:
Exterior: 815K = arrival blue
Interior: 522 = tan leather
In my opinion, the best colors GM offered on these trucks are 815K (arrival blue) like my truck, and the dark green variants they offered (9539 is what my Suburban has, but it seems they used other codes for other vehicles).
I personally like the tan interior over the grey, but the grey also looks good and many people prefer it. Grey goes with more exterior colors, but the tan looks good with either blue or green exterior to me.
we have the same favorite in colors
Surburban as a second car is also a good choice. As we can't afford to register an infinite number of vehicles, we limit ourselves to the two necessary vehicles and soon the oldtimer, which will only be registered seasonally (a fair-weather vehicle)
As we want still stay with non-shiny/non-metallic paint (couldnt convince the family) was a dark green no option. Family dont want to drive a forrest-office truck, the same is here for orange (garbage truck) or red (fire department) - so it remain the blue from the THW. It is maybe also as we have several family-members who are THW-members...
About the interieur - tan is a good combination with green or the blue. We have the grey interieur as we also have grey vinylseats. I tried to got used interieur here but there is nothing on the market. I had to import of USA which make it very expensive about the size. So we stay with grey and let the seats done by upholstery.
We had the bench and the complete Dashboard, doorpanels, sunvisors done here for our Chevy. About the Oldtimer value was it impossible to change the color or the design.
with no oldtimer restrictions i had let stich a big Chevy sign on the front
before... - the color comes not clear around - the new bench have the same color like the old one.
We choosed of a bunch of possibilities - its Mercedes car leather from the 70ths
With the Sierra seats i have all options open in color and design
But Upholstery will be the last what we will do.
We will go on with the front axle and the engine.
I didnt have made any big reseach for the seats as there is so much others to do before.
I absolutely had to have an American pickup... Now I just have to see how I can expand my knowledge to order the right spare parts. I get along with the technology but ordering the right spare parts is sometimes not easy. Returning imported parts is very time-consuming and expensive. As a rule, it's not worth it. My error rate is currently 1%. It doesn't sound like much, but if you add that to the total amount, it's already around 500 euros in the last three years. That was exactly the reason why the engines gone to an enginebuilder beside the warranty on the build.
