When is a Car "Level" - Home Front End Alignment

IMO, finding someone as far as todays techs who actually will perform all of the adjustments on one of these cars is the challenge. I had the wifes 97 bmercury sable in at a Firestone for 4 tires and 4 wheel alignment, the kid (he was about early twenties, maybe 24ish)told me that I "needed kits" for him to set rear toe..I said "Kits? the adjusters are right there..." BS artists are what they are charge you for some service that they only do one half of IMO. Point is, doing it "At Home" may be your best shot at getting the front end set up right.
