Available now at Quantum Auto Sales in Escondido, this Model 3 Long Range is priced at just $24,995 — making it one of the most compelling entries into Tesla ownership you'll find anywhere in San Diego County.

About This 2021 Tesla Model 3 Long Range

This 2021 Model 3 Long Range Sedan wears a clean white exterior and comes equipped with dual electric motors and all-wheel drive. At 101,745 miles, this Tesla is firmly in the "high mileage" category for a traditional gas car — but Tesla's powertrain and battery technology tell a very different story. Tesla Model 3 Long Range batteries are engineered to retain the vast majority of their capacity well beyond 100,000 miles, and the drivetrain has virtually no wear-prone components compared to a combustion engine. For an EV buyer in San Diego County, this represents exceptional value.

2021 Tesla Model 3 Performance and Engine

Dual Electric Motors and AWD

The Long Range trim uses dual electric motors — one on each axle — delivering true all-wheel drive with instant torque. In real-world driving, that means seamless, effortless acceleration whether you're merging onto Interstate 15 through Escondido or navigating winding roads through the inland valleys. The single-speed fixed-gear transmission means there's nothing to shift, nothing to wear out, and power delivery is always smooth and linear.

Tesla's Long Range variant was rated at approximately 358 miles of EPA range when new. Even accounting for modest battery degradation at this mileage, real-world range in the 280–320 mile window is realistic — more than enough for most San Diego County commuters, weekend trips to the coast, or drives out to the desert.

Tesla Model 3 Features and Interior

Technology and Comfort

The Model 3 Long Range is built around Tesla's iconic minimalist interior, anchored by a 15-inch center touchscreen that controls navigation, climate, entertainment, and vehicle settings. Over-the-air software updates mean this car continues to improve after purchase, with Tesla routinely pushing new features and performance improvements remotely. The Long Range trim also includes premium audio, heated front and rear seats, a glass roof, and autopilot — Tesla's advanced driver assistance system that makes highway driving significantly less fatiguing on commutes throughout San Diego County.

Tesla Model 3 Reliability and Ownership

What Owners and Data Say

The Tesla Model 3 has earned a strong reputation for low long-term running costs. With no oil changes, no transmission fluid, no spark plugs, and no exhaust system to maintain, the cost-to-own over the next several years is dramatically lower than a comparable gasoline vehicle. The most common owner concerns with high-mileage Model 3s center on panel gaps or minor interior trim wear — not powertrain reliability. The electric motors themselves are extraordinarily durable, and Tesla's brake system benefits from regenerative braking that reduces wear on physical brake components significantly. For buyers in Escondido and the broader San Diego area, home charging overnight makes daily operating costs a fraction of what gasoline would cost.

Frequently Asked Questions

Is the 2021 Tesla Model 3 Long Range a good buy at over 100,000 miles?

Yes — Tesla's electric drivetrain is fundamentally different from a gasoline engine. There are far fewer wear components, and battery packs on Long Range Model 3s have demonstrated strong durability well past 100,000 miles. Many owners report retaining 85–90% of original range at this mileage. Combined with low maintenance costs, it remains an excellent buy.

How many miles is too many for a used Tesla Model 3?

Unlike gas cars where 100,000 miles signals approaching major repairs, Tesla Model 3s regularly run 200,000+ miles with minimal drivetrain issues. Battery degradation is the primary concern, and it's gradual. A pre-purchase inspection or battery health report can give you added peace of mind.

What does the Tesla Model 3 Long Range trim include?

The Long Range trim adds dual electric motors for AWD, significantly extended battery range (rated ~358 miles when new), premium interior materials, heated rear seats, premium audio, and enhanced Autopilot capability — features not available on the base Standard Range model.

What is the charging cost for a Tesla Model 3 in California?

In California, home charging on a standard time-of-use rate can cost as little as $0.15–$0.25 per kWh during off-peak hours, translating to roughly $10–$15 for a full charge. At typical San Diego County electricity rates, most drivers spend far less per mile than they would on gasoline.

Does the 2021 Tesla Model 3 qualify for any tax credits or rebates?

Used EVs may qualify for a federal used clean vehicle tax credit of up to $4,000, depending on buyer income limits and purchase price thresholds. California also offers programs through CARB and local utilities. Consult with a tax professional and ask Quantum Auto Sales for details on current eligibility.
