I guess it is true that the car hobby can run into money, if you allow it to. However, if you think about what you are doing, you can arrange it so that at least you get most if not all of your money back. Set priorities. Catalog what absolutely must be done. Then what would be nice to do. With old cars, in most cases, 2/3 of the price is labor--much of that is labor that can be done by people who have little or no skill. Not to sound insulting, but that means just about every owner. With older cars, a person who can read and follow the instructions can do a fantastic amount of work just by following the tech manual, shop manual, etc. There is a place on line that has Chrysler Corp shop manuals on CD rom. If you have access to a computer, you can print out the pages from the CD rom, and have pages you can take to the shop, get dirty, and not worry about ruining an expensive book. While there are a few "tricks of the trade" that make the job go easier and faster, which are not in the manual, but by following what the manual says, you can generally get the job done yourself. I am continually amazed at the number of parts I can get by getting the counter man at my local full service auto parts store like NAPA, Carquest, etc, (not the discounters), to just look in the books. It works even better if I take the part in with me. With American cars prior to about 1980, there are a whole lot of mechanical parts that fit a whole lot of cars. A sharp counter man who will chase out the casting number can usually find a part that will fit and work correctly, where he could never find it by looking under 56 Imperial. You can buy enough tools to do most of the work for under $200 total. Try places like harborfreight.com. No these will not last for ever if you use them everyday as a professional mechanic. Yes, if you really abuse them, you can bend and break them. But they work just fine for the hobbyest who is not the Jolly Green Giant, and does not use 3 foot pieces of pipe to get more leverage. If you do not have a place to work, it does create a problem, but that can be overcome, too. I have done valve jobs with the car on the street. My brother has changed VW engines in apartment parking lots. If you pull somethng like that, it helps if you know exactly what you are doing, have the parts ready to go, and a pal or two who are also savvy. The key is to get it pretty well done before anyone finds management, and they get a chance to respond.
