I make about a 90 mile round trip commute from Riverside to Irvine everyday and have been putting a bunch of miles on my new duramax....I also have an 87 nissan sentra with 220,000 miles that is usually my driver. I need something with good gas milage and a little nicer than my nissan..anyone have any ideas on what I should get? A convertable would be nice..but then i dont want to spend a lot of $$$. used is a for sure!!
