I was a little apprehensive about buying a groupon for a 4 wheel alignment given the price was so low, but I have no regrets whatsoever now.
After the purchase, I googled Mac's Auto Care and I was pleasantly surprised how high their ratings were over the years. I booked my appointment and showed up on time a few days later. They got me in right away and started immediately. An hour (+) later my car was ready. The front office person showed me a readout of before and after measurements and explained the process. Fortunately, my car alignment was not too bad, which is what I expected given the tire shop said my tires were wearing evenly during my last couple visits. I bought my Tesla seven years ago, so the assurance of a verification check definitely gave me peace of mind.
I will be buying another Mac's Auto Care groupon in the next few days so we can check alignment for my wife's car. Highly recommended as long as you don't take all my next appointment slots. :-)
