New and used Tesla Model 3 Standard Range Plus for sale near Diamond Bar, CA

Best car buying experience I've ever had. Quick and easy without all the hassle of going back and forth with all the haggling. Staff was friendly and professional.

This car has been the best I’ve owned so far. Even if you aren’t looking at a Tesla, EVs in general are so much fun! I’ve had little maintenance in the three years I’ve had this car so far (tire rotations, wiper blades). Every major software update brings either new features or improvements.

Caesar was great from the moment we came to this location . He did the impossible and was able to get me approved for my dream car !! Highly recommend

If you want a maintenance-free vehicle, this is the closest thing you can find on the market. We’ve been driving the wheels off our Model 3 LR for almost two years. No gas stations, no oil changes, no fluid changes (unless you count windshield wiper fluid,) tires still have plenty of tread, brakes have barely ever been used (regenerative brakes are amazing,) the temperature in the car is always perfect when you get in, and no turning the car off, simply get out and walk away, the car does the rest. The only service we have done to this car has been tire rotation, and they come to your house to do it if you want! Charging at home means you never, ever have to worry about the state of your “tank” unless you’re on a trip over 350 miles. And then it’s a quick navigation to a supercharger for a few minutes; the car automatically does the math for you and determines the best places to stop along your route. Admittedly, the occasional supercharge on a long trip is the only downside and could be a dealbreaker for some. But we plan accordingly. Plug up the car, walk the dogs or grab a bite to eat. By the time you’re done, the car is ready to go! The loudest voices in the room are always the people that had the rare bad experience, that’s inescapable. Just know that they are the minority. This car has plenty of get up and go whenever you need it and rides smooth. I used to drive muscle cars, so not hearing all that engine noise took a little bit to get used to. But now I don’t miss it at all. In fact, now I’m mildly annoyed when I’m the passenger in a loud car. That’s probably also a sign that I’m getting older. If you’re on the fence about an EV, go take one for a test drive. Tesla doesn’t pressure you, they don’t even ride along with you. It’s just you and the car, so you can see for yourself. That’s all it took for us to bite. I can almost guarantee you’ll want one after you’ve driven around in one for fifteen minutes.

Caesar Quintero Always make it happen for us!! He provided great service and insight in purchasing our vehicle.

This is easily the most fun car I've ever driven; handling is great and it destroys muscle cars off the line! Very techy but fairly simple to figure everything out. I'll likely only ever buy Teslas now.

Maria Sanchez, Christian Campos and Sales Manager Rene were nothing but exceptional in the process of purchasing my vehicle. With the exception of a couple of other factors that weren’t pleasing, but these 3 individuals made it all worth while and a great car buying experience. Thank you!

It's the first time I've actually enjoyed driving. Before this I had a Civic, then a Sonata, and my first car way back was a Chrysler 300 (which was an absolute heap of garbage). After the 300 I was purely interested in reliable, economical cars that would get me from A to B with the basic amenities. The Model 3 was a step way above that, it's more efficient than any gas-powered or hybrid commuter car, it has a modest stylishness to it, and it has WAY more get-up-and-go than you'd expect, even with the single-motor package. The torque is instantaneous with no dead zones or gear changes. The handling is solid. There's a lot to love, including the infotainment system, built-in navigation, huge screen, etc. It was a lot to adjust to, going from a vehicle with tons of dials and buttons to just a screen and a handful of tactile controls, but I love it now. But one of the things I love most about it is that I can just open my phone and start the AC a couple minutes before I get in my car - In a city that regularly sees 110+ degrees, that is a GODSEND. I'm definitely an EV convert after buying a Model 3.

I highly appreciate the professionalism and efficiency at STG Auto Group. Maria made sure I was accommodated throughout the whole process. She was polite and always elaborated when I had questions. I’d highly recommend going to STG Auto Group for your next vehicle purchase. Ask for Maria, she made it easy.

Riding in this car will make you feel like you are a part of the future or hovering aboard a space ship. It truly rides like magic. I’m amazed at what this vehicle can do. The reliability and safety of this car is outstandingly outperforming every other car on the road. It does not require maintenance and every bit of the vehicle was built to guide humanity in the direction of 100% safe transportation. From my calculation on battery life, this vehicle will still hold a 250 mile charge after it’s been on the road for 600,000 miles. Considering sustainability of electricity and cost to charge- this car will save your pocket on energy costs and the earth from fuel emissions. The simplicity of the vehicle makes it easy to keep clean! Perfect 10/10 car.

Nice staff, great selection of Tesla vehicles. Good prices. It took a while to get seen but they were short staffed. Unfortunately I wasn't able to get the car. But I will be back for it soon.

Love this place , love the service, love how fast my process was to get into my M4 .best dealer I’ve ever made business, super polite , humble and very respectful, they even car washed the vehicle, man come one I was like whatttt!!! Super happy I drove out from Hollywood and I was not disappointed. Check it out for yourself!!!!!!

Albert was great in assisting me with my new Tesla! Couldn’t have asked for better service.

I’ve had my M3P for 5 days and I freaking love it! Controls take some time to get used to where everything is. I’ve had maybe 30 cars and this is my favorite by far. I highly recommend if you’re in the fence, just buy one. You only live once!

Great buying experience. I did take the car (BMW) to a BMW dealership for a concern I had with the car I bought at CarMax. They found something so then I took it back to CarMax to have it fixed (5-day money back guarantee and 30-day warranty) and CarMax took care of it at no cost and without any questions.

Ordered a Dodge 3500. And am waiting for it to be transported. The ill trade my car for a truck.

I went to the dealership yesterday with my brother and had help from Alex Santos. He had excellent customer skills and answered every question we had for him. He made us feel very comfortable and confident with buying the car. I surely recommend this place and sales representative!

2018 Tesla Model 3 Long Range RWD I purchased this car with a little less than 60k miles one and a half years ago for 21k. It now as 97k miles and the only maintenance I’ve done have been new tires and windshield washer fluid. Someone made a left turn in front of me and the car was already braking as I was lifting my foot off the accelerator. Quite literally saved my life. The suspension is tuned to be sporty, so it’s not a plush ride by any means, but it’s hard to beat at its price point in the used market.

They were very helpful and transparent about the cars we looked at. The process was very smooth. Did not try to guilt you into any other add ons that a big name dealership usually does. Would recommend to anyone trying to stay within their budget!

Absolutely love my Tesla. So much so we bought a 2nd one for the family. Smooth drive and zero maintenances in two years. Frequent software updates means I got new features long after purchase. Though I do suggest avoiding FSD. That's vaporware and will not be released in the lifetime of vehicles sold today.

This car is like something from the future. Five star crash rated, zero gas required, no oil changes or maintenance. And quick!!! This car moves and handles like a race car. This is the best vehicle I have ever owned. I’m excited to drive it and I love every moment of the experience
