He is correct, and honest also for not using scare tactics. It is a difficult job to do unless you have a lift and some experience. There isn't much room to get wrenches in there, and you need the experience to do the job. Given that todays labor rates are almost universally in the $75-$100 per hour, I would say that he is in the ball park. Also have him check the upper control arm bushings, since they have a tendency to fail often. Might as well consider having the entire front suspension checked while it is there. Only time that I would not suggest replacing anything that is even close to being worn out, is if you were going to be selling the car. On my cars, I replace parts that show even slight wear for safety reasons.
Use your vent windows! They make a huge difference just having that air movement. I wish that we still had them today!
all they need to be is past the bulb enough so that all the clam is behind the bulb and on the rubber. don't drive that with out a clamp. it it blows off at speed it will spray gas all over the engine and you will no longer have a car
