If you're searching for a 2021 Nissan Sentra SV Sedan for sale in Escondido, CA, this clean white example at Quantum Auto Sales deserves a close look. With 61,686 miles on the clock and an attractive price of $18,995, this is a well-priced opportunity to own one of the most completely redesigned compact sedans of its generation — a car that punches well above its class in refinement, technology, and value.

About This 2021 Nissan Sentra SV

The 2021 Sentra represented a massive leap forward from its predecessor, and this particular example wears its 61,686 miles comfortably. For a car that averages around 12,000–15,000 miles per year, this Sentra is right in the sweet spot — thoroughly broken in but with substantial life remaining. The crisp white exterior gives it a clean, modern appearance that holds up well in Southern California's intense sun, and the SV trim sits squarely in the middle of the Sentra lineup, hitting the ideal balance between affordability and features.

2021 Nissan Sentra Performance and Engine

Under the hood sits Nissan's 2.0-liter four-cylinder engine, producing 149 horsepower — a significant upgrade over the outgoing 1.8-liter found in previous-generation Sentras. Paired with Nissan's Xtronic CVT automatic transmission and front-wheel drive, this powertrain delivers a smooth, confident driving experience whether you're navigating the 78 freeway through Escondido, cruising down Valley Parkway, or making the run up to Temecula on the 15.

The CVT has earned a strong reputation in this generation of Sentra for feeling more natural and responsive than older CVT designs. In real-world driving, expect effortless merging, composed highway cruising, and fuel economy in the 29–37 MPG range depending on your route — impressive numbers for daily commuting in North County San Diego.

Nissan Sentra SV Features and Interior

The SV trim brings a meaningful step up in comfort and technology over the base S. You can expect features including an 8-inch touchscreen infotainment display with Apple CarPlay and Android Auto compatibility, a rearview camera, blind spot warning, rear cross-traffic alert, automatic emergency braking with pedestrian detection, and lane departure warning.

Inside, the 2021 Sentra surprised the automotive press with its genuinely upscale feel. The cabin uses soft-touch materials in key areas, the seats offer solid bolstering and support for longer drives, and the rear seat room is among the best in the compact sedan class. The overall cabin noise level is notably hushed for a car at this price point.

Nissan Sentra Reliability and Ownership

The eighth-generation Sentra, introduced for 2020 and carrying through 2021, quickly built a strong reliability reputation. J.D. Power gave the 2021 Sentra high marks for initial quality, and owner feedback consistently highlights the low maintenance costs, durable powertrain, and long-term dependability that Nissan compact cars have historically delivered.

Routine ownership costs are modest. Oil changes, tire rotations, and brake service make up the majority of scheduled maintenance at this mileage level. The 2.0-liter engine has no known major mechanical issues, and the Xtronic CVT in this generation has proven considerably more durable than CVTs found in older Nissan models. For a buyer looking to minimize ownership headaches, the 2021 Sentra is a smart, proven choice.
