I have an Eclipse 2007 is the inside of the Lexus IS 350 just as small? I like my car but wish I had looked more at the G35 Infiniti, Acura TL or the Lexus. Out of all of them though when it comes to purchasing a used one the Infiniti seems to be less expensive.

I just purchased a Lexus. I was between the Lexus and Infinity for a long time. Although the Infinity G35 is stronger than the Lexus, yet, the driving experience (from test drive) and the luxury inside is different. The Lexus is waaaaaaaay better. I advise you to have a look at the Lexus ES350, it is much more spacious and also more luxurious interior.

obviously..ya Lexus IS has more room since its 4Dr car and your Eclipse is 2Dr..
