Hey, chiming in here. We kept our 2000 323i until it had about 98,000 on it. CPO warranty ended at 100K. But now we'd wished we hung onto it for a errand car, etc. My X is getting spendy to fill up and I've been driving my Mom's 99 Civic to save gas...and I'd rather be driving the 323 than that Civic! Civic is relentlessly reliable but too much road noise for my tastes; but $35 bucks to fill up versus $85 + or -; not hard choice being unemployed! I'd hang on to your 2003 and drive it until it drops. With a great indy mechanic (have it thoroughly checked out now and then you'll know what you can plan for financially & mechanically for next few years) you can get another several years comfortably out of it and save some $ in the process over another car. And personally I'd probably never buy another brand new car again.

I don't have anything against Ford or Toyota having owned both but they feel bland compared to BMW's. After driving the Civic for 5 days and I get into my X or the 325 I realize why we own those 2 cars. Good luck!
