I own a 2002 LS430, silver, modern luxury package with the navigation. It all depends on what you are looking for in a car. What made you think of the LS? I sold my 2005 330i BMW to get this car. Yes, they are totally different cars. I like both. But after owning the LS430 for a year, there is little to complain about. Nearly all options are standard. No such thing as a base model LS430. I haven't run into any LS owners that had anything bad to say. If you want a smooth, ultra quite, comfortable seats, and good power, than the LS430 is a car you will not regrete. I've own many cars in the past five years (BMW's
3series 5series and 7series, Lexus LS400, LS430, GS300, IS300, IS350) and I like them all and each for different reasons. I have lots of friends with Accords and Acuras. They are very simular to Lexus owners. They like the reliable, safe, and solid cars both companies build. If you had the high end V6 Accord, I would wonder why you would part with it. I'm not saying both cars are the same, but I think both are good car for the price range. The bottom line: I would take the LS because you will not be looking for another car for awhile.
