Nice exterior and mill. The interior has much to be desired, though. Not only the color. With the exception of the wheel and guages. This somehow doesn't go together right...: ...With this. By the way, what purpose does that vacuum booster serve?:
That appears to be a genuine GM Air-Ride vacuum pump and tank. The pump ran off engine vacuum to charge up the air bag shocks (similar to Gabriel Hi-Jackers) for a better, smoother ride. Actually, it may not be called "Air-Ride," but that's what it was.
That must explain the reason he's not showing the rear of the car. He's afraid the trailer hitch would connote trailer pulling, devaluing the car.
Back in 1985 when I was 16, I looked at a 1970 Monte Carlo, not an SS, but it had a built 454 swapped in. It was in great shape, but I just didn't like the looks of the Monte enough to buy it. The guy who was selling it owned a tow truck company. I ran into him a couple years later and asked him about the car. He said he sold it and a few months later he got a call by the police department to pick up a car. When he got there he realized it was his old car. The guy he sold it to, ran from the cops, hit a wall at high speed and died.
The Monte Carlos weren't conceived for younger dudes. I didn't like them, myself. I was into the usual muscle car types. A guy in highschool drove one of those first series Montes and I thought him somewhat out of place. That's why, I know little about those, thick bumpered T-Birds, Cordobas, etc... they simply aren't young peoples' rides.
They may have been built for the Blue Hair set, but any car is what you make of it. My high school buddy John Hanna had a red '71 with black interior, it was roomy (I'm 6'6" tall) front seat and back, and it was fast, it had a 400/4-speed. But I didn't think he was out of place; rather, I thought the Chevrolet styling post-Bunkie Knudson was too conservative, even with the Chevelle, and the CamaroBirds were a bit too fattened up.
