The nice thing about the TL is everything is standard. The base model is going to have everything on it except navigation.The ES is a boring looking Camry with a better paint job and more leather. It is about as cheap as a Lexus gets. If all you want is a base model, you may as well get a BMW. At least that looks good.I've also driven the IS. The IS250 just plain sucks, it's that simple. Boring boring boring. I'm sure the IS350 is a little more entertaining, but again for that kind of money I'd rather have a BMW.After extensive testing of cars in this price range I purchased the TL. I was not disappointed. I also though the BMW was an incredible drivers car, and for the money you are talking about you could have the 328i with a couple of upgrades such as leather and automatic.Check out the reviews on edmunds.com.
