I had my g7 resprayed from lagoon blue to honda championship white.
The job was fantastic and in my eyes the car really stood out.
Would I do it again or recommend it... No.
Just stick to the oem colours, it's a pain in the arse if you need things spayed in the future because of accidents,stone chips etc...
Not only that when you eventually come to sell the car everyone takes a negative view to a resprayed car and always assume you're hiding something with fresh paint.
If the paints looking tired and you like the silver them definitely go for the same colour!
Just my past experiences and opinions!
