While that's a great price, they limit you to once every 6 months or 6000 miles. So if you hit a pothole and the car starts pulling 3 months after your last alignment your lifetime alignment policy wouldn't cover it. I will still consider doing that just because It's $200-300 per alignment in my area, so that price would be great based on my past alignment needs, but still not thrilled about the 6 month limit. On the other hand, I may just bring it in every 6 months to have it checked cause why not?
Edit: Just got a quote for my area and there's no mention of 6 months. The limit is every 6000 miles. We don't have to drive that much so it takes me about a year to get 6000 miles so I'd be limited to about one alignment per year. Still not terrible, but not great, in my opinion.
