I have had my avenger for 2 years now and I have put over $3,000 into it (not including routine maintance. I've had 4 new struts, 2 control arms, 3 tires, 2 rims, front brakes, hole in exhaust, and new locks. Now the sunroof is broken, radio reception is terrible, leak near drivers door, and my interior lights and some warning lights (low gas) don't work. The tires and rims are very expensive to replace and a tune-up and timing belt will run $300 and $500. The turning radius is also terrible and the V6 engine sounds strained.
I did fall in love with the styling. Mine is black with 17' wheels and fog lights. You don't see this car at every light and they aren't molested like civics. The interior has a good layout with plenty of room.
Moot point now that it is discountinued but, it needs more power and a lot better materials and build quality.
