Why not think about this seriously for a moment?
Let's see, it's got...
- a live rear axle. That's about as clever as a child's wagon.
- a 4.6L OHV/pushrod V8 engine with 3 valves per cylinder that produces only 300HP
- a 3500lb curb weight (that's over a tonne-and-a-half)
Technically speaking, it is a pretty lousy car when you consider that a company like Honda can get 240HP -- only 20% less than a the Mustang's V8 -- out of a naturally-aspirated four-cylinder engine that's 56% smaller at 2.0L. Or that Ascari can take a BMW V8 that's only 8% larger at 5.0L to develop 500HP. So, the Mustang's engine certainly isn't brilliant or clever, that's for sure. Maybe that's what he means by...*ahem*...it's a "dookie" car
So, yeah, you get bargain-basement engineering. But, you're paying bargain-basement prices. What more can you expect? And no one's going to look at a Mustang and say "What a lousy car". Not when it looks as good as it does.
