The service dept was super communicative and they quoted me 2.5 hours but it only ended up taking 1 hour. Chris was great in that he communicated with me early in the morning regarding the fact that they di me 2.5 hours but it only ended up taking 1 hour. Chris was great in that he communicated with me early in the morning regarding the fact that they did not have an loaner vehicles on hand. That was disappointing, but overall, not a dealbreaker as I understand that since my service only took a few hours it wasn't as necessary. Overall, however, Chris was proactive and followed up accordingly to ensure everything was okay. More
