Both of my cars are in the game; my daily driven Volkswagen Rabbit GTi (1976 Golf I) and my restoration project 1969 Corvette Stingray are in.
My personal Rabbit is a Westmoreland, PA, U.S.A. built 1983 Rabbit GTi made for the states, so there are slight differences. My front end has the square headlights and the later tail light bars in the rear. I did the GTI Cup race in a Golf V and waited until I got the Mars Red Golf I, just like mine.
My Corvette is in resto-modification shape right now. Factory it came out LeMans Blue... it's now black. It will be going back to LeMans Blue. I've got the engine pulled and there's no exhaust system in the car, the gas tank needs to be installed, brakes need to be looked at, and I need to buy a cooling system.
I pulled the engine because the prior owner helped it die out. I'm currently building a 383 cubic inch stroker for it. The engine fan and fan shroud on the car were the incorrect ones so I figured I would take the time to upgrade to electric fans while the car is down. The 383 is getting full length hooker headers that feed into 2.5" pipes all the way back into Spin Tech mufflers and megaphone out to 3" tips; the car should sound phuking mean!
The car's body isn't correct either. The "tunnel back" rear upper deck (that's the rear deck in the game which is flat and has the small vertical rear window with the two vanes that go down the L and R sides) has been replaced on my car with the bubble window on Corvettes from 1978-1982. Don't worry, it's returning to the tunnel back rear upper deck one of these years. The little window in the tunnel back pops out and installs in a little carry tray behind the seats. With the t-tops off, the rear window out and the side windows rolled down, the car feels an awful lot like a convertible in terms of airflow, but without the convertible insurance premium. My front fenders have been replaced so I don't have the 4 vertical "shark gills" either. Mine has the 1970-1972 "egg crate" style vents currently. Those too are going back to stock one of these years.
I've got 295/50-15 size Firestone tires on all 4 corners; those are getting replaced in the long term with ZR-1 sized 275/45-17 up front and 315/35-17 in back. My "little" 383 stroker motor is really being built up cautiously with longetivity in mind. I only want good low & mid range power out of it. It's going to be "old standby" if you will. My real goal for the car, years down the road, is to put a carbureted and supercharged all aluminum LS6 (out of a C5 ZO6) in the car mated to a T-56 (0.74 / 0.50 5th and 6th gears) transmission and 4.56:1 rear gears. Power goals for that engine? At least 600 horsepower, with more torque than horsepower, and redlining the thing around 8000 RPM.
The Golf I is closer to my Rabbit than the Corvette in the game is to my real Corvette, so I can't really say how the two of those cars compare. The Golf I feels close.
