With over 105,000 miles already logged, this is a highway-seasoned EV that's ready to keep delivering the performance and efficiency Tesla owners have come to rely on — at a price point that makes the premium electric experience genuinely accessible for San Diego County buyers.

About This 2021 Tesla Model 3 Long Range

This 2021 Model 3 Long Range is a well-traveled example of one of the most capable electric sedans on the market. At 105,607 miles, context matters here — Tesla's electric drivetrain is fundamentally different from a gasoline engine. There are no oil changes, no timing belts, no transmission fluid to degrade. The dual electric motors that power this car have far fewer moving parts than any combustion engine, which is a key reason why high-mileage Teslas continue to perform reliably for hundreds of thousands of miles.

The exterior presents in clean white, one of the most popular and timeless finishes in the Model 3 lineup. Stock #36345, VIN 5YJ3E1EB0MF079627.

2021 Tesla Model 3 Long Range Performance and Engine

Dual Electric Motors and AWD Capability

The Long Range AWD configuration is the sweet spot of the Model 3 lineup. Two electric motors — one on each axle — deliver instant torque and all-weather traction that rivals far more expensive performance vehicles. In practical terms, this means confident merging on I-15, effortless highway cruising through the inland valleys, and composed handling whether you're navigating downtown Escondido or heading out toward Temecula.

The single-speed fixed gear transmission means there is literally nothing to shift, nothing to slip, and nothing to wear out. Acceleration is linear, smooth, and immediate at any speed. The Long Range variant was rated for approximately 353 miles of range when new — real-world range at this mileage will vary, but Tesla batteries in this era have shown strong longevity, with many owners reporting minimal degradation even past 100,000 miles.

Tesla Model 3 Features and Interior

What the Long Range Trim Includes

The Model 3 Long Range comes loaded with Tesla's signature minimalist interior centered around the large 15-inch touchscreen that controls nearly every vehicle function. Features standard on this trim include premium audio, heated front and rear seats, a glass roof, over-the-air software update capability, and access to Tesla's Autopilot driver assistance suite — which includes adaptive cruise control, lane centering, and automatic emergency braking.

The cabin is spacious and quiet in a way that combustion car interiors simply aren't. Road noise at highway speeds is noticeably reduced without an engine competing for your attention. Trunk space is generous, and the front trunk (frunk) adds practical cargo flexibility that sedan buyers don't typically get.

Tesla Model 3 Reliability and Ownership

The 2021 Tesla Model 3 sits in a generation that had worked through many of the early build quality concerns that followed the original launch. By the 2021 model year, panel fit, interior quality, and manufacturing consistency had improved significantly. Owners of this generation frequently report strong battery retention, software-driven feature improvements that arrive automatically, and low overall maintenance costs compared to any gasoline alternative.

Common ownership considerations at this mileage include tire wear (Teslas are hard on tires due to the instant torque), brake pad inspection (though regenerative braking means pads often last far longer than expected), and a battery health check, which any qualified EV technician can perform. The absence of oil changes, spark plugs, coolant flushes, and transmission service makes the long-term cost of ownership genuinely lower than comparable used gas vehicles.

Frequently Asked Questions

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

Yes — more so than most gas vehicles at the same mileage. Tesla's electric drivetrain has significantly fewer wear components than a combustion engine, and the 2021 Long Range battery has demonstrated strong longevity. A battery health check is always recommended, but many owners report minimal degradation well past 100K miles.

How much range does a 2021 Tesla Model 3 Long Range have?

When new, the EPA-rated range was approximately 353 miles. At higher mileage, real-world range may be modestly reduced — most owners with 100K+ miles report ranges still in the 300-330 mile zone, depending on driving conditions and climate.

What does the Long Range trim include compared to the standard Model 3?

The Long Range adds the second electric motor for AWD, significantly extends the battery range, and includes premium interior upgrades like heated rear seats, a premium audio system, and improved materials throughout the cabin.

Does this Tesla still qualify for any tax credits?

Used EVs may qualify for a federal used clean vehicle tax credit of up to $4,000 depending on income limits and vehicle sale price. California also offers state-level incentives. Consult a tax professional to confirm eligibility based on your individual situation.

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

Unlike gas cars, there isn't a hard mileage ceiling that signals trouble for a Tesla. Battery degradation and tire wear are the primary concerns at higher mileage. Many Model 3 owners routinely drive past 200,000 miles with the original drivetrain intact.
