Advice sought for a B-body: '68 Satellite Unmarked Cop Clone

Hello fellows:

I realize this is probably better on forbbodiesonly.com, but I'd appreciate the advice of my fellow A-body friends (you fellows convinced me to buy my '69 Valiant, and I don't regret it - in fact, today was the most fun I've ever had driving it!)

That said, I had an interesting experience today - I went to see a fellow in the south end of town to buy his used SBP 14" rims for my Valiant.

Unfortunately, it turned out that the rims were LBP from a '68 Satellite 4-door. However, next to the rims sat the Satellite itself - it is a very accurate clone of an unmarked/undercover '68 Belvedere from our local police department, and - strangely enough - I'd actually seen photos of it on CopCarDotCom's Fotki page and SERIOUSLY lusted after this thing.

I had no idea I'd actually wind up driving right to it today!

Problem is, I'd always thought it was a genuine cruiser, and the owner didn't say it was a clone from a civilian Satellite. I decoded the fender tag as follows:

CAR: Plymouth Belvedere 4 Door Sedan
ENGINE: 318cid 2-bbl V8
TRANSMISSION: 3-Speed Automatic
TIRES: 7.35x14
BUILD DATE: November 07.
AXLE: 2.76 Rear Axle Ratio
INTERIOR: High Trim Grade
PAINT: Monotone Medium Green Metallic Paint.
OTHER: Medium Tan Metallic Upper Door Frame Color.

MOLDINGS:
25: Drip Rail Mouldings
55: Body Side Mouldings
78: Wheel Lip Mouldings

ABC OPTIONS:
A1: 26in Radiator
R1: AM Radio
S1: Air Conditioning
X1: Tinted Glass (all)

abc OPTIONS:
m6: Driver's Outside Remote Operated Mirror

The body side and wheel lip mouldings are long gone. It was put together as a pet project of a vocational auto engineering school, so it's not that bad. Missing headliner, trans pan needs attention, A/C disconnected, needs exhaust. Paint job looks like good paint, but the application has been amateurish. Needs weatherstripping.

He told me he wants $4,000 for it. I was game if it had been an actual RK41 car, but it's an RH41. The police radio, gun rack, and siren are all period pieces; I assume sourced from retired department units. Radio blankoff plate is also in place.

Question is: Would you do $4k for a rough civvie cop car clone? The clone bit kills me, but I realize that the chances of finding the real thing are highly unlikely, and even if I do find one, it'll probably be a marked unit, which I would rather not have (a restored police car makes for a strange and conspicuous daily driver, and I'd constantly have to worry about some idiot trying to remove magnetic covers over the lettering). That said, I'm sorely tempted, even though I have no right to spend $4k right now. It also fits me WAY better than the Valiant, and the coke bottle hips of the '68-70 B-body 4-doors are probably my favorite bit of automotive styling in history.

Advice MUCH appreciated!
