My mom's official car is a Honda Accord EX. It's very nice, no complaints about the gas mileage, roomy, comfortable even on long trips, and lots of cupholders. I like it.
My dad's car would seem to be a big ugly maroon Chevy Astro, more recognizable as that van everyone in California had in 2000. It was my grandma's, we used to have a white one which we recently sold. It's... useful for lots of passengers, I guess. Feels like a bus though. Don't know much about the gas mileage. I wouldn't want my dad to sell it for a truck though.
My sister's car, for which she only has a permit as of March 31, 2007, is I believe a Ford Escort. I won't complain about it because as soon as she gets her license, it's my alternative to the terrible bus rides to and from school (but only until this semester's end). It's maroon, two doors, with Jack Skellington mats I got her for Christmas.
My car, is, for the second post today, a Karmann Ghia. It's retro. Stick, fairly efficient on gas, would look incredible with a makeover and some tweaks in the interior, awesome leg room in the front, brand new brakes... It's not a whole lot right now, but I love that car. If you missed The Hopeful thread (as if anyone ever does,) I have photos,
the front and the
back.
To answer your Malibu question, I couldn't tell you if I've seen one. Don't get an Astro or an Escort. You probably won't find one, but Ghias are cool... but not really family car material. The Accord is a nice family car though... and the EX has a moonroof!
