I am having all the services of this car since 2002, especially through Dennis Mitchell. Dennis is a great person and is very kind. I was never disappointed. All other services are great too. That's why I always come here to have my car serviced. Today when I came to have oil change, the oil change manager Matthew told me that the coolant engine fluid level is not very good, there are some back stuff sitting at the bottom of the coolant tank. I did my coolant fluid change last June-July 2014. Matt said they might not have cleaned the tank before filling the fluid as it has only been some months. He spoke to Dennis about it. Dennis told me he would get back to me for this service. As I am a valued regular customer and changed the coolant only some months ago, I sincerely hope you will take of this and change the fluid.
