Friend of mine wants it BAD.
He is afraid its gonna end over his budget

Yeah, I'm not seeing anything to pick on except the fully painted underbody and what may be a scratch/dent above the left quarter scoop, which may just be an unfortunate reflection.
The underbody is basically a non-issue unless it's being judged for OEM correctness, and to me the V88 is a bonus.
Also seems well-documented; another bonus.
Being a '70, that styling may be a break price-wise; but a no-excuses car, even with polarizing styling, probably won't sell cheaply.

BaT...nothing goes for a price that makes sense. Look at what the OBS Ford trucks have been bringing. Beyond stupid.

Nice Looking Original Car
Love the factory paperwork.
I will be watching it to see where it goes.

Nice car.
I'd be tempted to have the undercoat installed. I'd definitely get a set of rims and hubcaps and switch back and forth to feed my whim of the day.
Odd seeing the clear glass & A/C combo.
I'd probably put the original gears back in too.

I'm not going to repeat what others have already said about the car.

if your friend wants it, he shouldn't bid until the end. Yes, I know the clock resets two minutes if a bid is placed in those two minutes but, bidding early does nothing but start to show his hand.

Best of luck.
