2015 Toyota Sienna

If you're looking for one of the most reliable, practical, and well-kept vans in the country, this 2015 Toyota Sienna is worth a serious look. Offered in a timeless gray-on-tan color combo and backed by a pristine Clean Carfax, 1-Owner, Washington-owned history, this Sienna is the needle in the haystack. No accidents, no damage, no open recalls, no funny business—this is the exact kind of used vehicle that holds long-term value, especially when you're talking about Toyota's bulletproof 3.5L V6 engine and proven drivetrain. Unlike many minivans on the market today with sketchy multi-owner histories or former rental abuse, this one has the clean local Pacific Northwest pedigree we always preach about at Supreme Motors. It's one of the most mechanically sound, meticulously kept examples we've come across in recent years, and the condition clearly reflects the easy life it lived here in Washington’s mild, non-corrosive climate.This Sienna is equipped with Toyota’s tried-and-true 3.5L DOHC 24-valve V6 engine mated to a 6-speed automatic transmission, a combo known for lasting well past 250K+ miles with minimal major issues when properly maintained—something this van has clearly benefited from. The power delivery is smooth, quiet, and efficient, yet responsive enough when loaded with passengers or climbing inclines. The engine bay is clean and dry, and the transmission shifts crisp and seamless. Mechanically, it’s rock solid, with a full inspection already performed by our in-house ASE-certified techs at Supreme Motors. The suspension is tight with zero clunks or worn bushings, brakes have plenty of life, and tires have excellent tread depth left. There are no warning lights, no leaks, no mystery smells—just a dialed van that drives like it’s ten years newer than the model year on the title.Interior-wise, this Sienna offers a highly functional and spacious cabin layout with seating for up to eight. The tan cloth interior is in phenomenal shape with minimal wear and no funky stains or odors—no kids or pets tearing this thing up, which is rare for a van of this class. The captain’s chairs in the second row allow easy access to the third row, which folds flat for more cargo space. Dual sliding rear doors provide effortless access, and the visibility in all directions is excellent—something Toyota has always prioritized in their van layouts. Power driver seat, tri-zone climate control, steering wheel audio and cruise controls, and backup camera all make it an ideal family hauler or road trip machine. The insulation inside is top-tier for this segment, keeping it quiet at highway speeds, and the climate control system gets ice cold in seconds.The exterior condition is just as impressive. The classic gray paint is still deep and consistent with a clean clear coat and no signs of oxidation or fading—another benefit of that local garage-kept life. No dents, no mismatched panels, no hail damage, and no signs of repaint or touch-ups. Body lines are laser straight, panel gaps are factory consistent, and it’s clear this wasn’t the van that got beat up in a school carpool line. It’s sitting on clean OEM Toyota 17” alloy wheels that are free of curb rash and wrapped in newer all-season tires with even wear. Headlights are clear, all plastics and trim are intact, and even the roofline and moldings look showroom. It’s the kind of van that looks better than many 2019+ models we’ve seen at auction with half the miles.Another major selling point for this Sienna is the unbeatable ownership cost. Insurance rates are lower than most SUVs, fuel economy averages 25 MPG highway, and the maintenance costs on this generation are dramatically lower than newer models with more electronics and tech packages that tend to glitch out over time. There are no turbos, no air suspensions, and no CVTs to worry about—it’s built with the same philosophy Toyota used for the golden-era Camry and Land Cruiser platforms: simplicity, reliability, and longevity. The undercarriage is clean, free from any corrosion or frame scale, further proving this was not exposed to East Coast winters or snow-salted roads. Washington-owned Toyotas like this are known for their clean underbodies, strong resale values, and dependable performance year after year.At Supreme Motors in Auburn, Washington, we specialize in handpicking the cleanest, best-optioned, lowest-risk vehicles for our clients—and this Sienna checks every single box.

It's the kind of vehicle we put our name behind and one we’d gladly sell to a friend or family member.Bottom line: this is the ri
