Hmmm... for a DD
DDs get...
run into by stupid drivers
rotted out by salt in the wintertime
backed into by old ladies at the store
doors slammed into by stupid people
...stuff like that.
Do you really want to sink a lot of money into something that'll see that kind of stuff?
For a 'ecoturd' I'd go for a Subaru anything, preferably non-turbo for daily beater duty. AWD is great in the wintertime. A GM 3800v6 anything would be great as well. I consider the SC'd 3800s more 'modern muscle' so to speak and don't consider them to be 'daily beater' type cars, unless you get one that's cheap to buy and isn't in great shape. Ditto with the SRT-4, Cobalt SS, Ion Redline (actually faster than the SS, yes... a Saturn...). Ford Focus SVTs are pretty quick, but rare and are known to have clutch issues. A regular focus still handles like a go-kart and in my experience is alright (no muscle car, but still moves out of its own way). My buddy has a 5-door focus and I LOVE it for a daily beater.
If you want more money for the Jeep, do what I do and get a $500 craigslist car. Drive it, and if it needs anything more expensive than a set of tires sell it for $500... on craigslist. lol.
