Used Porsche convertibles for sale near Pomona, CA

Aaron has been very courteous and professional during my contact with the dealership. He's gone above and beyond in his approach to customer service.

What can I say, the benchmark of sports cars. I have a 4S Cabrio. I chose the 4 as I like all-wheel-drive, even in Florida. Better grip. The S also has more horsepower. Build quality and fit and finish our superb. The ultimate sports car without all the problems of the Italian cars. You’d be hard to find a car with better handling and Performance. The look is timeless. There’s no mistake at what you’re looking at when you see a Porsche. Great car.

Buying from Quantum Cars has been a fantastic experience. Everyone was professional, reliable and efficient while maintaining a good attitude the whole time. By far the best car buying experience I’ve ever had. Thanks Quantum Team!

992 C2S. Best performance car I’ve ever drivin. Can’t think of any negatives. People complain about the price but 100,000 for a suv or loaded pickup is ok. Took years to finally acquire this car , happy it finally became a reality.

Friendly, professional and knowledgeable. Christian my sales person was a chill non pressure guy that wanted to help answer question. I would highly recommend this dealership.

This is my 3rd Porsche and this time I chose the 911 T. I wanted a xxxxx to the wall driving experience in the Smokie Mountains near my home. The T does not disappoint. It performs flawlessly. It hugs the corners -I can easily take 25 mph at 50 mph or more in perfect control. The engine/weight ratio gives more power than can ever be realistically used even if you have a long stretch that is police free. Overall it is a thrill to drive, the cabin is comfortable without being fussy and it growls like a caged tiger with the sport exhaust.

Great honest sellers who are very familiar with the collector car market. They have rare classic and exotic cars in their showroom located in Old Town Orange.

Own this classic while the price is still affordable. The car to own if you want to invest in a car the the price will keep appreciating. It is the ca the is and will always be THE 911

Still reviewing them have had good contact so far. They were great about bringing my other vehicle to my home.

Just got a 2019 Carrera 4 GTS. Seems great so far, very fast and handles great. GTS model seems to be the best bang for the buck as far as power and options that are included

GREAT DEALS. AWESOME SERVICES. THANK YOU JOHN AND JAY FOR HELPING ME WITH MY NEW CAR. I WOULD DEFINATELY RECOMEND THIS DEALER. IT WAS A SMOOTH PROCESS. THANKS AGAIN

What can you say about any 911? The one I test drove was the S. It’s just the perfect sports car. Light, just enough power to go fast, not overwhelming. Comfortable, quiet, composed at any speed. The soft top is so quiet. Almost like a regular top. With the top down, you can still hold a somewhat normal conversation at highway speeds. Just the perfect car for a cruise or fast run on a sunny day.

I had a great experience with Porsche Riverside. Rob made sure that I got a very fair deal. I'm thrilled with my new, beautiful car.

Marco delivered excellent service!! Overall great customer service and very knowledgeable. Will continue scheduling with him.

Had this car for about 2 years but need a car that is going to be better in the snow. Have had no complaints what so ever about it. Drives great and sounds amazing as well.

Amazing dealership! The buying manager gave a very fair offer on my car. I would 100% recommend this dealership to anyone. Thank you Quantum Car Company!

The Staff at Porsche Long Beach replied promptly and answered all the questions that I needed answered. Maybe I'll have a chance to do business there another time.

Excellent sales ambassador who met my needs....thank you to Darrin. The video went great!

I have always wanted a 911 Targa. I've always been inspired by the airy glass canopy in a refined and reliable sports car like the 911. I have wanted one since it was introduced. The glass canopy allows the outdoors in and provides plenty of light when driving through Mt. passes and canyons. I have been wanting to drive the famed 993 911 as well. So this opportunity gave me the best of both worlds.

Excellent follow up with my inquiry about the vehicle -easy to schedule an appointment -greeted by sales rep Jamey Perez on arrival -cars that I looked at review well -easily transitioned to financial with Michael - overall excellent experience

When you buy a Porsche 911 you buy it because of its performance. My car now has 96,000 mile are runs and drives as it should. I do several DE track days every year. It has never let me down. It is amazing to drive, steers like it is on rails, stops on a dime, and goes as fast as I need it to go. What a great car!!

Had really pleasant experience purchasing my daughter’s first car here! They have a very nice selection of inventory to choose from and their website is straight forward and give you lots of information to make an informed decision. Staff is very friendly and never once did we fell pressured. Highly recommend this dealership.

It looks just as good as a 911 without the sticker price a head turner whenever it’s on the street I am always asked if I want to sell the car the answer is no way

Would recommend Porsche Riverside . Great service, best price,so many choices here. Tony Nguyen so friendly, nicely and helpfully. Not rushing and gave very good deal. So happy for my purchased.

Ryan truly did his best to work with me, because of Ryan I would definitely go back to this dealership and purchase another vehicle. He truly did his best to keep me happy with the amount of my trade in and with the amount of the purchase price of the vehicle I purchased from him. Met my payment at what I was looking to pay , he truly made me and my 2 boys feel welcomed and I truly appreciate you Ryan for all of our deal. Thank you

Second Porsche Boxster this lifetime. Fully equipped top down fun with the finest in modern technology. Best value sports car on the market for reliability and motoring enjoyment.

Tony Nguyen in sales at Riverside Porsche was extremely knowledgeable about the porsche market place. I bought a 2015 911. His knowledge and customer service skills were impeccable. Also Kevin in service and Andy in finance were a pleasure to deal with and very honest and upfront about everything

One of the best sports cars available today. Comfortable daily driver with canyon carving capability. Still available with a naturally aspirated gasoline engine and a manual transmission. One of the last (mostly) analogue delights at a (relatively) affordable price.
