How much would it cost to retrim the blue bits of the interior in grey?? I think a grey/black interior would work really well with the Jewel Violet rather than standard blue/black interior which would be a bit bright to 'go' IMO.
Only problem I see is, being a complete step away from the norm, it might be a bit more difficult to sell the car on in JV since it's more of an aquired taste than a standard bold solid colour like White, Red, Blue or Black.
Cheers,
Grant
