This reminds me of my Dad's 2001 Silverado. Tailgate fell off so Chevy repainted tailgate which he didn't want cause it was red which we all knows fades quickly. It matched perfectly so he had them agree to repaint if faded different but he wrecked it in rear quarter of bed which needed a special repair as it cracked again a perfect match. Fast forward and Dad passed on so truck sat then brother bought it but now original paint is finished. He called me asking history since he lived out of state when dad first bought it so I passed this on and he stated I must of been mistaken cause tailgate and bed match but rest of truck is faded on top of all panels. Point is a good paint shop will match paint but it will fade differently depending upon color. My red Tacoma was to be repainted with less than 2 years old after paint was coming off after each wash but an accident week before got sections repainted much to my dismay. Never did fade evenly but paint from Shop never did fade so it looked terrible so I let truck go back. Major accident, bad Toyota paint and Toyota fought me on everything after warranty. Toyota wouldn't even replace windshield with debris in between glass since new.
