Used Cadillac cars for sale near Diamond Bar, CA under $1,000,000

My experience at Sierra Nissan of Duarte was absolutely amazing. My sales associate & finance manager Melvin Tjia was VERY knowledgeable and made the entire process seamless. I will most definitely continue to highly recommend all my friends and family to shop here at Sierra Nissan!

The interior is like a space ship! The interior leather is just the color I was looking for. It is so smooth riding and quiet!

I had the best and worry less experience with this dealership, it took only 2 hours since I stepped in till I left wit my brand new Mercedes Benz, Ali, the sales representative is wonderful, He is so welcoming and kindly found the exact car to my taste and an awesome test drive experience over the best view of Long Beach and ocean, found a GREAT deal and negotiate pricing and conditions, David, the sales manager was really generous, he generously added an extra deal and made it even greater for me, the whole process of documentation and contract went so smooth and fast and they clearly described and clarified all terms and numbers, car delivered clean, shiny with no detailed missed and Ali went trough all features and described them patiently, the other five star thing was that they DIDN'T try to sell any additional non sense and I REALLY appreciate that, I'm so happy with my new Mercedes Benz and highly recommend all my friends and family to go to Mercedes Benz of Long Beach for their next car buying,

I’ve owned Cadillacs since 1979. This is by far the best fit for size and comfort. Not a “boat” but big enough for a family trip.

Lisa Briton provided excellent customer service and kept me informed about the repairs to my vehicle. She was very knowledgeable about the mechanics of the vehicle and what needed to be repaired and explained very thoroughly.

I wanted this car... Value for money is excellent for this level. The twin turbo V6 is plenty powerful... The quality and attention to detail is apparent. Rides great! Handles great! Can choose between touring and sport mode mode ..sport mode tightens everything up and makes the exhaust note more aggressive..And it's American.

The best dealer Crestview Cadillac west covina. Very nice service and friendly.The best dealer . Make sure you look for Avia Yin she very nice and helpful . Totally happy😍😍😍

I'd rather go to the dentist than go through the hassle of buying a car. The staff at Crestview Cadillac changed everything. I'm 64 so I've bought cars before I know the sing and dance of car buying. Jason was fantastic, everyone I came in contact with at Crestview Cadillac was top notch in customer service. I was promised a price and was given that price. If you are interested in buying a car, new or used give Crestview Cadillac a chance. I know it's a Cadillac dealership but it's a different way of buying a car. It's the way it should be. Give Jason a call at Crestview Cadillac he'll take care of you.

Crestview Cadillac provided the easiest, most seamless, and best car-buying experience I’ve ever had. Jason Kim, our Sales Consultant, was knowledgeable, professional, and maintained excellent communication throughout the process. He took the time to ensure we understood all the features and details of our new car before we drove off, making us feel confident and well-prepared. Additionally, Peter Mark, the Sales Manager, went above and beyond to secure the best possible deal for us, working diligently to apply all available discounts. I highly recommend Crestview Cadillac and especially Jason and Peter for anyone looking for a top-notch car-buying experience.

As I walked- I felt the ambiance that I was looking for. It’s a small dealership & I felt comfortable. No pressure. So we purchase with Crestview Cadillac.

Avia is perfect professional. She was very patient with us and made the process very easy. A+ service. She goes beyond. I hope to do business again.

I have a 2025 lyriq for 6 months and have fallen in love with this car. Trouble free, comfortable, powerful acceration in a beautiful body. A few minor things, like having a bar graph and miles remaining instead of a number percentage for the state charge and could use slightly tighter steering adjustment. Otherwise it's the best driving vehicle, ICE or EV that I have owned. Do not hesitate.

I leased a 2025 and in May of 2025 and I now in October 2025 have just over 5K of trouble free miles, no issues what so ever. Love this aar so much I will most likely buy at the end of the lease. It is the most comfortable vehicle I have ever driven. The other review about the brakes, they most likely turned off the regenerative braking system and then forgot to use the brakes. I say that because when my was inadvertently turned off the same thing almost happened

The CT 5 Sport is a hot ride. It’s loaded with all the bells and whistles, from Supercruise assist to the hottest styling of the dash, it’s truly phenomenal! The change between touring and sport is seemless, there are so much to say about this car and not enough room!
