Since as far back as 2000 Lexus has been the top-selling luxury brand in the U.S., a position it appeared the Toyota premium division would be to hold on for years to come. Despite top marks in dependability and satisfaction surveys, Lexus recently conceded its number one spot to BMW based on year-to-date sales, and could be opening the door to the year-end tally as well.

That hasn’t stopped the company from increasing prices on most of its core models for 2010, with prices announced today revealing hikes from between 0.7 and 1.8%. The affected models include the IS 250 and IS 350 sedans, IS 250 C and IS 350C convertibles, IS F high performance sedan, SC 430 convertible, as well as the RX 350, RX 450h and LX 570 SUVs.

While prices have gone up on most models, there have been some upgrades as well. Lexus’ Safety Connect telematics system is now offered as standard on most non-navigation equipped models, while the full Lexus Enform with Safety Connect is standard is standard on most of the models with navigation. Complimentary one-year trial subscriptions of Lexus Enform and Safety Connect are included.

The IS 250, IS 350 and IS F also enter the 2010 model year with an updated premium audio system with an optional hard disc drive navigation system, while the IS F gets new 19-inch wheels, a limited slip differential, and foldable rear headrests.

For 2010, the SC 430 receives new 18-inch wheels, side mirrors with puddle lamps, an updated navigation system and updated Mark Levinson audio, as well as some new colors.
