I have used STEM's services a few times now and every time, I am left satisfied and with a little bit of knowledge. Recently, I scheduled an oil change and noticed a small noise coming from the front end of the vehicle and asked Matt to check it out. He informed me of the issue and gave me a suggestion on how to have it fixed. He also did the Oil change in Buffalo Winter Weather... He is completely equipped to handle the elements and is more than happy to do the work!
