Yet again, it's still a mule, guys, so don't get too in a bunch about the random fin & light on the trunk. Think of it like the way the prototype headlights used to look driving around, even pretty late in the game.
Could be like that, could not. Could be a mixture. Engineering mules are just that, mules of cobbled together parts. Hence the V6 car with an SS front clip, etc. We'll see.
Otherwise, it'll be a great car. Just hold your horses on nitpicking weird parts on a mule
