Honestly...how good was the 318...mpg / durability / hp

I've had a bunch of 318s and some performed better than others.
But the most memorable was in an 85 or 86 fifth Avenue I had. From a performance standpoint it was terrible. a lean burn choked gutless wonder.
But on highway driving at a sustained 65 mph it came it at almost 25 mpg!
25 mpg out of a brick shaped,comfy as your living room couch cruiser was fantastic.
