Making slow but steady gains in the U.S, the mid-sized 2005 Hyundai Sonata sedan is starting to put a dent into Toyota's and Honda's reign in the domestic market.  With a class-leading warranty, more affordable price tag, and a long list of standard features in the base model, the Sonata is popular with drivers seeking quality on a budget.  There are few changes in 2005.  The luxury LX trim gets an auto-dimming rearview mirror, and there is a new GLS Special Edition trim that offers heated front seats.

The 2005 Sonata comes in base GL, GLS, and LX trims.  A 138-hp, 2.4-liter I4 sits in the base, coupled with a 5-speed manual transmission.  An optional 170-hp, 2.7-liter V6 is standard in the GLS and LX, and is coupled with a 4-speed shiftable automatic.  The front-wheel drive sedan is wider than a Camry and is noted for its spacious front and rear legroom and a 14 cubic-foot trunk.  The base model GL offers full power features, cruise control, and a CD player, while the GLS upgrades interior materials and adds map lights, heated mirrors, and rear cupholders.  The LX goes whole hog with leather, a power driver's seat, and garage opener.  Dual front-side airbags are standard, but ABS brakes and traction control are offered only as options.  Rear seats split-fold 60/40 for extra trunk space.

After a 2002 upgrade, the Sonata has improved its styling and performance, and few drivers find fault with its handling and smooth ride.  Though somewhat harsher than its competitors on the highway, the 2005 Sonata stands out for its spaciousness and 10-year/100,000 mile warranty.  Drivers like the long list of standard features and say the interior ergonomics are easy and convenient.  Downsides include overall seat comfort (not enough padding), a labored 4-cylinder engine, rapid and undeserved depreciation, and disappointing fuel economy.
