the new focus won't get here till 2010 or 2011. back to reliability my dad has a coworker that had to get a chevy dealer to buy back his truck for constant problems. the 99 silverado my dad had was horrible.
i guess just our experiences then. never had an issue with any chevy. except my yukon recently where it blew a tranny. but that was competly my fault as i flushed the fluid and forgot to put new fluid in. so i blew it. other than that i have had no issues with any GM vehicle.
