i had someone back into my black mica speed3 last summer and smash the front fender. i too was worried about paint matching. when i got the car back i was amazed at what a good job the shop did the car actually looked better than factory bc after painting i had them colorsand the whole thing. the repair looks perfect, and the shop i took it to stands behind their work and throws in a free wax/detail every 2 months for the entire life of the vehicle! make sure you find a good body/ paint shop and the repair will be just fine.
even if the color is not 100% the exact same as the rest of the car (which is probably how it was from the factory lol) they will blend from the roof, fenders, and anywhere else thats near the damaged area. this will blur the lines dramatically between where new and old paint meet. then if they colorsand the whole car, which is not a big deal for them bc they are doing it on the new paint anyway, it will make sure all the paint has an even and smooth finish.
