I bought a groupon and it was a decent deal, each time i made an appointment they said an hour, never finished in an hour, average 1 1/2. My mistake I bought a second groupon, and they changed the pricing so now higher for each oil change then the dealership, took it in and again was told an hour, went walking and returned hour and 40 later to find they did not have my filter, it was over two hour when finished. next appointment I asked to make sure the oil filter was in stock when i made the appointment and was asked why so explained what had happened and was told it would be ready in one hour, so dropped and again told one hour and went our walking, returned 1 1/2 later and they had not started and the women at the desk said well you left , yes i left but asked and told one hour. so again waiting. And she was "my bad"
