What car should I gid rid off?

Sorry this is a long post, so bear with me.

I am told I have to get rid of one of my vehicles, as I have lost my storage for one of them, and now have too many at my house.

I need some input on this issue, as its a tough decision for me.

I have whittled the choice between two vehicles (out of five I have).

Cars at my house:
69 Roadrunner - Project(not getting rid of).
74 Duster (not getting rid of)
67 El Camino (my first car, still a project, and not put-together enough to even think about getting rid of).
76 Chrysler Newport - Bought this car for $100 cash. Its a boat!
2000 Mitsubishi Eclipse - My current 4-cylinder Daily Driver.

The two cars I would even consider getting rid-of are the Eclipse and the Newport. One of them will have to be my daily-driver (about 20 mile commute each way each day). I do drive my duster at least one day a week, so I will balance my driving between the duster and another vehicle.

The pluses and minuses I have been able to figure out so far:

Newport:
+Easy to work on and tune up!
+Very comfortable, power-seats, tilt and telescope steering, cruise-control
+400cui of Mopar Big block torque
+Boils one tire with ease (Smoke show!)
+It floats down the road (smooth ride).
+No car payment, and pretty cheap insurance.
-Sucks the gas big time.
-takes a city block to park, and doesnt fit in compact spaces.
-Four doors, doesn't attract the ladies. It looks like grandpa's car.
-Needs to be smogged before I can get it tagged.


Eclipse:
+Good on gas (4cyl) and small.
+Good Stereo.
-Still have a little more to pay off , but very little.
-Insurance is high (they consider it a "sports car")
-I know very little about working on it beyond changing the oil.

More Information:
I bought the newport with the plan to eventually yank the 400 engine and 727 tranny to rebuild to eventually go in the Duster. But the 360 in my duster runs so freakin awesome, and the car handles great right now, I dont think I need to upgrade any time soon. I did replace the old dried-out valve seals on the newport 400, and put a new carb on it. It runs really good now. The Newport also has a little over 60,000 original miles since it was new, so it would really be a shame to junk a car with mint interior and very presentable paint for the powerplant it holds.

So what do you guys think, get rid of the Eclipse or the Newport?
I can post pic's if anyone wants. Thanks for reading my post.
