Larry is exactly right about the simplicity and durability of the 240D BUT for your commute I would recommend a 300D (1980 through 1985) with an automatic transmission. There is NO way you want to commute in stop n go traffic with a manual transmission. Keep in mind that the '80/81 models are not going to be turbocharged. My 300D with 234k miles has some issues but it runs/drives out good and makes a good commuter. Heck, it does not even use oil between oil changes. The only real issue is that the tranny is in high by the time it gets to around 40 mph. I just drive it like that. Just makes for slower acceleration. Try to find the absolute best example of whichever model you choose.
