I have a new Monday through Friday commute starting which is 140 miles round trip. I just picked up a 2004 Lesabre with 38k for $3k which is a great commuter in my mind however I would hate to put so many miles on this great find so quickly. I'm thinking of picking up a compact beater civic, focus, ranger, swift, etc for $2k or less to drive back and forth. Handling any repairs myself will not be an issue. So what does everyone think should I drive the Buick into the ground or pick up a beater?
