X2, love my 08 LTZI still love my Malibu. I have the 08 LTZ 3.6 v6 . Had it for a year now and I put all highway miles on it. I get the great MPG at usally 33.2mpg going around 65 to 70mph with the cruse control on. I still cant hear any outside noise unless the usally big trucks. My car was a great buy for me with the power and sporty look in and out trust me i still like and love my malibu.
