Coils get hot and any cracks that appear or internal components failing due to manufacturing flaws/age/etc. allows current to leak causing either complete failure to fire by not passing enough current to the plugs to generate a significant spark, or intermittent failure where it fires only when it wants to.
Before you buy the car, have someone test out the coil's resistance levels as per the manual. You can also buy a coil and try it, but it's up to you. Unless you trust the seller, there could be a whole lot more wrong with the car not firing then a coil.
Have you checked the error codes on the PCM? You can borrow a OBD-II reader from a parts store (pay a deposit and get it back when done), or you can do the Dodge key dance. Turn the key on-off three times quickly and read the two digit blink codes on the check engine light. You can do this over and over to make sure you get them all. It will blink quickly then pause. Count the blinks between the pauses and write down the two digit pair. Blink-pause-blink blink is a 12 (ignore it). 5 blinks pause, 5 blinks is a 55 which means end of codes (ignore it). Here is a thread that covers what each of the codes mean:

If you get an 11 error code, then most likely one or more of three things is bad on the car - the timing belt, the crankshaft position sensor, the camshaft position sensor. The last two will prevent the coil from firing. The first one can to, if it is broken or has so many teeth gone that it slips so much the timing is gone and it cannot decide when to fire.
