2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. Iām tall and there is plenty of room. The seats are incredible! Canāt wait to take it on the roads in winter.

Purchased a 2013 Audi Q7
I saw the Cars.com listing for a Audi Q7 at Mercedes of Encino and contacted them. I worked with Patrick Lau. From start to finish the deal was handled quickly and efficiently. Even though I was located over 100 miles from the dealership everything went perfectly.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Paul Joval is awesome!
Paul Joval is awesome! He's knowledgeable without being pushy. Me and my husband had texted Paul earlier in the week regarding a SUV we saw online. When we went to the dealership, Paul had the vehicle out and waiting for us to see! Billy in finance was also a gem to work with. Billy ensured that we had everything covered within our price range. Just an awesome overall experience! Thank you

I recently purchased a Mercedes Benz Sprinter Van from
I recently purchased a Mercedes Benz Sprinter Van from Valencia Mercedes Benz Dealership, and I couldn't be more thrilled with the entire experience. Ethan Zinshteyn and Sales Manager Daniel Medina provided exceptional service from start to finish. Ethan was incredibly knowledgeable about the Sprinter Van and took the time to understand my specific needs. He patiently answered all my questions and ensured I was comfortable with my decision. His professionalism and attention to detail made the buying process smooth and enjoyable. Daniel Medina, the Sales Manager, also played a pivotal role in my purchase. He worked diligently to secure the best possible deal and went above and beyond to ensure I was satisfied with every aspect of the transaction. His commitment to customer satisfaction is truly commendable. The team at Valencia Mercedes Benz Dealership exceeded my expectations in every way. I highly recommend Ethan Zinshteyn, Daniel Medina, and the entire dealership for anyone looking to purchase a Mercedes Benz. Their dedication to excellence and customer service is unmatched!

This review is long overdue.
This review is long overdue. Dominique Torres has assisted us multiple times since we got our EQS about a year ago, and each experience has been outstanding. Sheās always been a pleasure to work with ā easy to reach, quick to respond, and proactive in providing timely updates. Most recently, I had an issue with a headlight. I called Dominique in the morning, and she told me I could bring the car in later that same day. I stopped by House of Imports after work, and Dominique promptly received the vehicle and took care of everything. She even offered a courtesy car in case mine needed to stay overnight, but the issue was resolved in about 30 minutes, and I was back on the road in no time. Thatās what excellent service looks like. In recent years, Iāve noticed a general decline in customer service across many places ā but not here. Itsās refreshing to work with someone like Dominique who consistently goes above and beyond. This is exactly how you retain clients and turn them into repeat customers.

Good for buying cars, not so good for maintaining.
In 2008, my folks bought a new Chrysler Pacifica Limited. The car sales man was great. He knew all about the car and showed us everything about it. The dealership it's self is beautiful and super clean. They also have AWESOME cars inside in which you can sit and mess around in. The overall rating is a 4 BECAUSE, it is so hard to get a hold of these guys to take the car in. We've called 4 or 5 times to only leave messages that have never been responded to, so we are planning on just going there whether they want us to or not!
