Actually the 76-80 Volare/Aspen was a decent car. At least compared to the other vehicles in that time frame. Sure it had it's share of issues and had some rust problems but what car, regardless of mfg, didn't at that time?
Various members of my family and friends have owned many different year/model Volare's and Aspen's ranging from standard models to the Road Runner, Super Coupe, and Aspen RT. I had one as well. A 76 Volare Road Runner( bought in 85 while I was in high school ). That was a great car and at many times I have wished I never sold it. I wouldn't rate it up there with the real MOPAR muscle cars and true Road Runners I have owned but it was a really nice car. My Aunt and Uncle just loved their 78 Volare 4-dr w/ 225. They ran that thing well into the late 90's before it finally had enough with well over 400K on it. I almost fainted when I heard they replaced it.
If the OP can get that car for say $400 or so and it actually runs and all the fluids look good there is no reason not to buy it. Give it a good once over and look for rust issues, check the brakes, make sure everything on the dash works, etc... and if it all checks out there is no reason not to buy it. A couple hundred more in maintenance after to change fluids, belts, and hoses. maybe get a new battery, and it could be a half way decent bomber. The carb is a breeze to rebuild if needed. The Volare's with the slant six got 1/2 way decent MPG when properly tuned.
Here is my 76 V-RR( bottom of page ). Horrible picture but the only one to survive. Mine had the rear deck lid spoiler, the rear side window louvers, and the wheel well flares( can't see in the photo ), Only exterior options it was lacking were the front chin spoiler and T-Tops. Inside it had bucket seats with a floor shift console( auto ). The car was special ordered w/ the 8 1/4 posi rear end and also manual steering( power was standard ). I got it from the original owner.
I rebuilt the engine for better performance and had the vehicle painted a really cool custom scheme as you couldn't find the factory stripe kits at that time to restore it( funny but I can find them easily now all this time later ). Originally mine was black w/ the red/orange/yellow graphics. For the custome scheme I went with black again as the main color but then it had silver and plum crazy stripes on the hood and deck lid.
When the paint job was cleared I added mother of pearl frost blue to the clear. This gave a great effect of the color changing depending on the light. It could look black( night ), metallic bright blue( bright sunlight ), or a dark metallic purple'ish( dawn/dusk ). It was a great paint job. I used some earlier model year RR graphics and emblems on the doors( can't see in photo - really poor quality - sorry )and the famous standing RR in the circle on the rear spoiler. It really made for a cool look. It would run high 14's to low 15's @ 90 MPH so it was no slouch although not a beast or anything. Just a very good car for me.
The tip another poster gave about the ballast resistor is the best and most accurate comment in this thread I read. Definitely keep not one but two in the glove box. Cheap part that as said just decides for no reason to die. Quick and easy to swap though as they are right on the fire wall almost in the middle( favors passenger side a bit ). One bolt in the middle and then 2 plugs attaching to it.
I say if the price is right and the car seems ok go for it.
My 76 V-RR...
Originally from the factory my 76 V-RR looked like this minus the front chin spoiler and the aftermarket wheels( not my car just an example ). I would have restored to original had I been able to find all the stripes and decals but as said at the time you couldn't get them. Now it is easy. I would definitely buy another one of these if the right deal ever fell in my lap. I keep my eyes open looking...
