When I first read the specs for the new IS, I was certain the most popular model would be the 350, but now, after seeing them

both side-by-side and appreciating the 250 for what it is, I could easily see it selling just as well or better than its more powerful stable mate. For me, however, it would be IS 350 or nothing, and this would be a big jump for a six-time BMW, one-time Audi, and one-time Jaguar owner to make. But I don't think my preference is unique, having scoured internet forums on a regular basis and witnessing the adoration performance sedan fans have for this new Japanese upstart. How many times have I read potential buyers say, "If the IS drives as well as the 3-Series I'm going to buy it?" And that's how Lexus stands to gain ground in a market segment where its previous IS merely floundered. The IS 350 should not only satisfy most BMW 330i aficionados in the corners, after leaving them breathless at takeoff, but its refined mannerism should make Mercedes-Benz and Audi owners sit up and

Its touch-sensitive DVD-based navigation system is also easy to use and very effective, plus it includes a backup camera that is not only cool to show off to friends but also could potentially save the life of an otherwise invisible child wandering behind your car. Being a parent, this last item becomes mandatory once lived with, as is the powered rear window sun shade. Side window shades, like those on the LS, would be appreciated too.
