I actually quit going to Leif Johnson and switched to Covert because they sucked. It's funny that you said that about Covert. Oh well, I guess everyone has had different experiences. I took my SVT in 3 times for a problem I was having (was bad O2 sensor) and they said they couldn't find anything wrong because the computer didn't come back with a code, and "one of their guys drove it and said it seemed ok to them". Then I had one of their service advisors ask me what kind of gas I put in and I said I had only run premium since I bought it (new) and it never had a drop of anything else. He proceeded to tell me that was the problem and that I shouldn't put anything but regular in it until I pointed out the fact that the gauge even says "Premium fuel only", there were other probs. with LJ. It took Covert 2 tries to figure out what the problem was, and they were only able to get it after a light came on (problem had been occuring for over 2 months). Anyway, for alignments, I have always gone to Brake Specialists. They offer a lifetime warranty on their alignment, so I figure that's pretty hard to beat, and they've done them one several of my vehicles in the last 7 years and I have no complaints. Just a thought.
