Tan, amazing. Red, amazing. Light gray, amazing. "Ivory", amazing. Light brown, amazing. Maroon, amazing. Green...well, needs to not look like puke and coordinate with the rest of the package. Same with blue. I test drove a black interior Aston and it just felt boring.
My Honda has a gray interior, and if I ignore the ugly black trim in the car I think the gray leather looks stunning. The usual gray fake leather offered in Porsches is also a stunner IMO. Almost went for a Subaru with brown leather interior instead and I was honestly comparing it to my Aston Martin's interior...if you told me it was a Lexus I would believe you. They've come a long way. However the exact same car in black leather just feels completely boring.
Best looking car (that you can actually buy) all around IMO is the Lexus LC, I would rate the exterior maybe slightly below Aston Martins (still stunning but a little polarizing at the rear) but the interior is OH MY GOD I AM IN HEAVEN. No manual transmission though, that's why I have this.
