Didn't expect incredible service as we didn't purchase the car from them, but didn't think it would be this bad. Brought car in for scheduled Friday appointment and told we'd get it back same day. No one called with an update , had to call multiple times and then were asked to leave the car through Saturday. No one calls all day Saturday, had to then call them over and over and be put on hold and hung up on only to finally get through and hear that they need a part and the car is undrive-able--and they're all out of loaners, but don't worry, car will be ready Monday AND loaners will be back then too. Call Monday afternoon (of course they don't call us with an update as they promised) and are told parts come in on Tuesday and who knows how long the car will be, and loaners are booked for weeks. No explanations, no transparency, no one cares or could be bothered to call us, even though we were told Friday 'they weren't busy.' All we wanted was a truthful diagnosis on the problem so we knew what to expect. Apparently that's too much to ask.
