Almost nobody can compare these honestly — dealers usually sell one brand or the other. Doug’s in Lynnwood sells and services both, so here is the straight version, and you can drive a used Mazda6 and a used Hyundai Sonata back-to-back in one appointment.
The used Mazda6 (2018–2021) is the driver’s pick among these midsize sedans; the used Hyundai Sonata (2020+) is newer on average, with a bigger 16.0 cu ft trunk and a hybrid rated around 47–52 mpg combined.
Mazda discontinued the Mazda6 in the US after 2021, so Sonatas are generally the newer used option with more remaining basic warranty.
Doug’s in Lynnwood services both brands in-house, so either sedan comes with a shop that knows it.

Yes. Doug’s Mazda and Doug’s Hyundai are one lot family in Lynnwood, so one appointment covers both — back-to-back, same loop, no second dealership visit.
It depends on age and mileage, not just brand. Mazda’s 3-yr/36k basic and 5-yr/60k powertrain coverage transfer in full. Hyundai’s 5-yr/60k basic transfers too, but its 10-yr/100k powertrain warranty applies to the original owner only. We’ll show you the exact remaining coverage on any specific vehicle.
Check the EPA figures in the table above — hybrids are the standout savers where available. Routine maintenance costs are similar for both brands, and both are serviced in-house at Doug’s.
We sell and service both, so we have no reason to steer you either way — the facts above come from manufacturer specs and EPA estimates, and the better choice genuinely depends on how you’ll use the vehicle.
Same lot family, same visit, no repeated negotiations. Tell us a time that works and we’ll have both vehicles ready.
Up to 3 vehicles, one visit, back-to-back — even across Mazda and Hyundai. We’ll have them ready.
The estimated sales tax shown uses a 11.2% combined rate typical for the Lynnwood, WA area. Your actual sales/use tax is determined by the address where the vehicle will be registered and may be higher or lower. A negotiable documentary service fee in an amount up to $200 may be added to the sale price, as permitted by Washington law (RCW 46.70.180).
Government fees are NOT included in any price or estimated total shown — including title, registration, licensing, plate, and emissions fees. These are collected at purchase in addition to the amounts shown.
Monthly payment estimates are calculated over 72 months at 6.99% APR with a 10% down payment, and assume good credit (top-tier lender approval). The amount financed is the estimated total — vehicle price plus estimated sales tax and the documentary service fee — minus the down payment. Government fees (title, registration, license) are not included and are due at purchase.
The APR assumption is benchmarked to BECU’s published used-vehicle loan rates for well-qualified borrowers on comparable terms, and we update it as published rates move. BECU is an independent credit union — it is not affiliated with this dealership and has not sponsored or approved these estimates; your lender and rate may differ.
Payment estimates are not an offer, quotation, or commitment of credit and are not a lease offer. Financing is subject to lender credit approval; not all buyers will qualify. Your actual rate, term, down payment, and monthly payment depend on your credit history, the lender, and the final negotiated price. Advertised estimates are available to qualified buyers on the terms stated above.
Prices and availability come from our dealership inventory system, refresh several times a day, and are shown with the time they were last confirmed. Despite our efforts, errors can occur and vehicles can sell at any time; all prices and availability are subject to prior sale and to correction of typographical or system errors. Please confirm the final price and availability with us before visiting.
All used vehicles are sold subject to the terms of the FTC Buyers Guide posted on the vehicle, which is part of your contract and overrides any contrary statements. Ask us to see the Buyers Guide for any vehicle before purchase, and whether the manufacturer’s original warranty still applies.
