Thanks for the support, Max 98059.
Prafeston, even though blue is my favourite colour I didn't really like that light blue interior shade either, I prefer a medium bright "electric blue" like I put on the exterior. For the longest time while I was building it I kept thinking a black interior would be much more desirable but by the time I got to the interior I'd spent all the money I'd budgeted for this car so I hesitated to replace it. When I saw purple carpet was available I decided I'd try combining the light blue interior with purple, and to my surprise it completely changed the way I feel about that light blue. To me the purple contrasts really well with the blue interior and now I definitely prefer the light blue/purple interior over a black one.
