"Excellent customer service. Overall great service. Highly recommended. Extremely satisfied and will definitely keep coming back."
"How often would you say you love going to your mechanic? This is the place!! It starts at the front counter. They always remember me and they never make me feel uncomfortable (even when I can't exactly explain the strange noise in the engine). Every time they make time or try to make accommodations for whatever is going on with my car. They will go over all problems and costs in detail with you before they do it. The mechanics are all super friendly and do their jobs really really well. I am so fortunate and so happy to have found such an amazing place!!"
"Simply Smog Valencia Auto Performance made my experience great during my visit. I went in to get my Smog checked. Took 30 minutes from check in to payment. The staff was very friendly and professional. They have a waiting room where you can sit, use WiFi, and watch tv while you wait. Reasonably priced and they had an online coupon when I went. So that was awesome. Will go back there when needed."
"Great shop! I went in to get my brakes inspected and replaced and they were honest with their prices which weren’t bad at all. Comfortable and clean waiting room while you wait!"
"Perfect place! Friendly staff, and was able to get my smog done in no time. The lounge was comfortable and AC was perfect. What a place to be and know that your car is being taken care of. Thank you!"
"I recommend Simply Smog Valencia Auto Performance to anyone who needs automotive service. I have been coming here for about 8 years now. They are fair, fast, and always friendly, which are a rarity these days. Sam Farah, in particular, is a great asset to this business. Keep up the good work!!"
