The service shop at Mills was amazing. James Dent was accurately able to dignose the leak from my Acadia and fix it promptly. It’s been a few weeks now and there absolutely no leaking. The service was fast and very reliable. The lady at reception had an uber to pick me up as soon as my car was ready. The service advisor Kyle, was very friendly and has great communication skills. Highly recommend this service shop for all your needs.
