1932 buick 57s 4 dr sedan

The car is in great shape, have used for weddings and staging at home for local garden tour. Just seems I have no reputable person locally to work on it. Seems I know more than they do. Have been told it needed a new right front king pin. My book tells me that may seem what it is but only needs repacking. As you can see in the background of the pictures I am more of carpenter I built that garage and turned a 1837 house into a victorian. The car has always been in a heated garage since it was redone in the 1990's Has 3 chips and a bubble in the paint. No pitted chrome, No holes or wear in upholstery. I bought this for my 60th birthday I am almost 76 and have 4 cars and a 3 car garage. Paint bubble less than 1/4 inch by radiator cap, been there since I bought it. very small chips at each end of hood hinge, mechanics laid the hood back instead of using designated bracket. And the pictured chip I assume was a tire change. Mechanic recommended an electric fan, Charged me $650 and I noticed he put it on backwards. the original fan has a simple method of lubrication. I still have it in perfect condition. I guess I thought it would be simple for a mechanic to work on it but unless they can plug in a computer to it they are dumb. If any questions feel free to ask. The car doesn't idle properly seems to race after you drive it for a while when you stop at a light. I don't think the mechanic drives it enough to test it. And I heard he said I mess with it too much. No he isn't solving the problem but wants to put it on me. I am out of options to find a reputable person.
