The batteries on these newer cars are such a pain to change out! Woke up Monday morning with a dead battery. I simply did not have time for this today! Went to price a new battery on google and saw this service. What a great idea! I could still work (from home) and not waste my time working the the dumb car! The tech showed up in a couple hours and was done in maybe half an hour. It would have taken me a half day to figure out how to get one out and back in. You have to run to the auto parts store (in a different car the first time) twice. Once for your new battery, and again to recycle the old one and or get a core return... After buying a battery, the additional cost for the mobile tech was about $100. Well worth my half day or so. Also, a three year warranty! He said he would come back if there are any issues. Super pleased. This guy saved the day!
