How much extra are you willing to pay for 2007 Lexus Es350 over 2007 Avalon Limited

Depends on what you like.
Lexus is better than Toyota; t's not just a different name from the same company.
The quality and comfort is much greater, service is slightly better and the performance of the car is top-notch.
The Avalon is tricky, though - it's kind of like a bridge between the two. Avalon it the top Toyota, but could be a low end Lexus.
Th ES 350 is an awesome car - If I were you, would go for it, as long as the financing isn't a stretch.

Buying the AVALON will save you $7,000 dollars over the ES350. Both of these cars share a common platform with each other and the CAMRY, SOLARA, RX350, HIGHLANDER, SIENNA.

About a $1.75. Look they are the same car just with different names. Lexus is to toyota as Cadillac is to Chevy, Buick, Pontiac. It's the top of the heap. If you compare option to option you will find you are paying a lot for the name. get the avalon. You have the same quality, and service with the toyota that you would receive with the lexus.
