Wire feed is awesome. MIG baby. Hobart=Miller, so if you can find a Hobart for a good deal, do it. If you have 220 in your shop/garage, take advantage of it, get a 220v welder. Some may argue that you can get a better penetrating weld with a stick welder, and they are correct, until you get a good 220v wire feed welder. At that point, you can weld anything you would need for your Jeep, and it is far easier and much nicer looking. Don't waste your time with flux core wire, just get a tank and use a shielding gas with regular wire. 110v welders work okay for smaller stuff, but a nice 220 will work as good in those situations (turned down of course) and will work much better on thicker materials.
