Yes I could imagine you are detailed oriented as well on the tech sector side of things. It's my wife that actually picked the interior, I showed her the photos above and she instantly said... "get this one". I asked her why, she said "I don't know but this one has better interior". She has very fast intuition. I then asked her if she likes the extra white leather. She said "yes definitely".
We don't have a lot of money so we budget best as we can, all of our cars we got 2nd hand. However despite that we try to make the most out of the options we get. Case in point:
R34 GTT - Our had lots of options including Xenon light (same as GTR), harder factory springs, bigger disc, better factory sound system, auto on light, etc. Options that I am aware not with the car is sun roof, skirts and rear spoiler.
LC90 - Factory leather (I didn't know it exists before, but I guess it does), sunroof, emu springs, etc. Not aware of any option that is not with the car.
955 Cayenne S - Not a turbo but options make its like a Turbo, Staggered Sport Techno wheels, Full leather interior (e.g. dashboard, sides are full wrapped), Eisenmann exhaust tips, Xenon, etc. Option that I know not in the car are sunroom and auto on light.
I think the M5 will be fun to discover which option it has when we get it. For us who can't afford the check the tick box options to include when we buy a new car, so our fun bit is discovering which tick box was ticked when the 2nd hand car was new ?
Good night and Merry Christmas!
