Looking for a Porsche dealer near San Dimas? Porsche Ontario is a family-owned Porsche dealership on Inland Empire Boulevard and part of Walter's Automotive Group. San Dimas drivers visit us for the latest Porsche models, Porsche Approved Certified Pre-Owned vehicles, and service from a recognized Porsche Classic Partner workshop.
From downtown San Dimas, we're roughly 15 to 20 miles away via the 57 South and the 10 East. Browse our inventory and start your finance application online, then make the drive when you're ready.
Porsche Ontario is a 2026 Edmunds Five-Star Dealer and a Cars.com Consumer Satisfaction Award winner. Both honors are based on verified customer reviews, so they reflect how real shoppers felt after their visit.
We are an official Porsche Classic Partner. In 2021, our team won the inaugural national Porsche Classic Restoration Challenge, competing against close to 40 dealerships with an RS-inspired 1989 911 Targa G-Model. If there's an air-cooled 911 in your San Dimas garage, the specialists are close by.
Our story started in 1960, when Walter Kienle opened a European repair shop in Riverside. Five years later, he was selling the cars he had been fixing. Today his son, Steve Kienle, leads the family-owned Walter's Automotive Group.
Life in San Dimas moves between the 210 commute, weekends at Puddingstone Reservoir, and quiet streets below the San Gabriel Mountains. These four models fit that rhythm.
A midsize luxury SUV with standard AWD and available E-Hybrid power. Select trims tow up to 7,716 lbs.
An all-electric compact SUV with 800-volt fast charging, ideal for overnight home charging.
The rear-engine icon tailored for Glendora Mountain Road and climbs toward Mt. Baldy.
An all-electric sports sedan built for trips west toward Pasadena or south on the 57 into OC.

Porsche Approved Certified Pre-Owned vehicles are used Porsche models inspected by Porsche technicians and backed by factory coverage. Most are checked against a full 111-point checklist.*
Coverage includes a 2-year, unlimited-mileage limited warranty that begins when the new vehicle limited warranty ends (or on the date of sale, if it has already expired), plus 24/7 roadside assistance.* Eligible vehicles include the current model year and the 13 prior model years with fewer than 124,000 miles. Our pre-owned selection can also include the 718 Boxster and 718 Cayman. A pre-owned 718 is a smart way to put a mid-engine Porsche in your San Dimas garage.

Porsche Ontario sits on Inland Empire Boulevard, just off the 10. From San Dimas, most drivers take the 57 South to the 10 East and arrive in about 25 to 35 minutes, depending on traffic.
San Dimas keeps its small-town western feel. Downtown has wooden sidewalks and old-fashioned storefronts, and the city's equestrian roots show up on the horse trails at Horsethief Canyon Park. Weekends might mean fishing at Puddingstone Reservoir, a hike in the foothills, or a ride from the San Dimas Metro A Line station, which opened in 2025. It's a city of about 33,000 people where local relationships still count.
That's the kind of relationship we aim to build. Our team works with every kind of San Dimas driver, from first-time Porsche buyers to longtime owners adding a second car to the garage.
