I took one of my cars to the shop ONCE. My 85 GT developed a clutch issue and I was stressed out in college and very busy and just took it to the local guys who I went to high school with, lived two streets over while in HS, and our parents were friends. They were a little older and had a decent shop by this time. Got the car back and out of curiosity I jacked it up to take a look. The transmission had never been out of the car....they just adjusted it yet charged me for a clutch...and these were people I knew.
That was the one and only time I have or ever will take my car to anyone. You can't even trust a mechanic you SHOULD be able to trust. But, because I do everything myself I just learn how to do things I have never done so now there is no part of the car I cannot do myself....engine, transmissions of all types, differentials, paint and body, upholstery and electrical and glass. I can do it all, and all by myself because even though I have helped tons of people there is no one available if I need something....so I have just learned to do everything myself. It just takes some thought and creativity to solve the need for a third hand.
On an engine being a two man job....NO, except for one thing. Circa 1982 I had to take the new engine out of my 66 coupe because the shop had done the heads wrong for rail rockers and the valve stems were cut too much. Stuff I did not know at 18, and one weekend on the way home from UT with a good buddy's now wife the ticking got louder until the engine swallowed a valve. Car was towed 50 miles home.
The following weekend I got home to take out the engine. My dad was outside and asked if I needed help. I told him no but if I did I would call him. About 45 minutes later I called him and he said "I knew you would need help" and I replied "yes, to take the hood off". Everything was disconnected, I just needed the hood out of the way to hook up the hoist. It took me no time to hook up the chain hoist and then the engine was out....all in a bout an hour. The only help you need is to get the hood off....but since then I have developed a way using ratchet straps to remove and install hoods by myself.
