5.0???????
 

I was going to school when I get a red light I looked in the parking lot next to me and see a 5.0 mustang.... well when I took my right I got a better view of it it looked like a mustang just the trunk it looked like a really old grandma car like how the back of the trunk molds out a little to fit the spare tire. sorry that's a pretty crap description, but just wondering if anyone ever seen one or know what they are??

It sounds like you're describing a Lincoln Mark VII. Those are based off of mustangs, have that molded rear, and also have the 302HO and share alot in common with mustangs. They look kinda like a old person's car (well...it's a lincoln) but they're damn nice i must say.
