I went in for Smog Check after seeing the reviews on Yelp. Everyone was friendly, but when they went to check me out, said my car was low on fluids and charged $20 to top off the fluids. (I thought it was $20 including the smog check-then that would have been in line) I thought it a bit pricey to "top off" fluids, but had a massive headache so allowed them to do it. I will give it to them this time, but anything in the future, I will ask to see the levels and watch them put the fluids in.
