Hi Kevin ,paint technology has greatly improved thankfully, my wife’s car needed wing and door painting and the body shop were able to match new paint to existing faded paintwork that was 9 yrs old ,I was hesitant at first but the results were perfect ,regards Dan
You're welcome, good luck with it! It's worked on the other cars, i'm not sure if the Jag seats are wildly different but would think there is a fairly common adjustment mechanism sold to a variety of manufacturers so hopefully the same method will work across marques.
