GI Auto Salvage Co Inc: 85 Bloomfield Avenue, Pine Brook, NJ 07058 (973-227-1100)
I took my first trip down to this place. A friend of mine's father suggested it to me. He gets most of his spare Civic parts from there.
The junkyard was broken down into 2 sections: 1 pick and pull (a lot of complete neglect) and 1 fenced-off area that you are only allowed into with permission from the owner or accompanied by an employee.
As far as cars go, it can be broken down into 4 categories.
1) Pickup trucks. Lots of them. Especially Ford F series. And of the F series, especially F-150s dating back to the very early 80s if not before that. I'm not a pickup specialist.
2) Japanese and Korean compacts and subcompacts. Accords, Civics, Elantras, whatever. They have a few. I saw a very clean and relatively unmolested fifth generation fifth gen Civic. There was a Subaru Outback, too. And while not a subcompact, I even saw an Eclipse.
3) Various not-german European cars. Sure there were a few Mercs and E28-E30 BMWs, but there were a whole hell of a lot more styled-by-LEGO Volvos and a fairly solid assortment of early Saabs.
4) Escorts, Focuses, Escorts, and Escorts. Seriously, I saw at least 20 of them sitting side by side.
And now for the bitchin' cars that don't fit into any of these categories, or maybe they do but are just bitchin'.
240SX

The entire car is pretty untouched. A few pieces missing here or there, and one crack in the center rear light thing that says 240SX, but otherwise really complete.
Nissan Pulsar

This is an N13 Pulsar, but not just any Pulsar. This is the high performance SE model that would've come with the CA16DE or CA18DE- peaky 1.6 or 1.8 liter engines depending on model years. Unfortunately, somebody took the amazing little engine and less amazing transmission out of the poor little Pulsar.
Subaru Alcyone SVX and Porsche 928

Yes, the Subie has the 6 cylinder EG33 still in it. Practically untouched, too. It should be a direct swap to any first generation Legacy or Impreza, for anyone so inclined. I didn't look at the Porsche.
1969 Olds Toronado

This is one of the first FWD American cars ever, for those not in the know. In typical American muscle fashion, however, Oldsmobile Toronados were equipped with the fearsome 455ci (7.5 liter) Oldsmoble Rocket V8 putting out 375 ponies and 425 twisties. Can anyone say torque steer?
This Olds happened to still have the engine and transmission, but not much else. This car was pretty thoroughly picked apart. The rear trunk has some pretty bad rust and there's a lot of broken glass. The interior was absolutely demolished. It was also, very unfortunately, the vinyl top instead of the hard top Toronado. Vinyls became optional in '69. At least it's big enough to 69 in the '69.
Mark IV Lincoln Continental

This car is, without a doubt, the coolest car at the junkyard. Sitting proudly in the center, this magnificent, inert lump of imposing Detroit iron vigilantly overlooks the pick and pull area of the yard, waiting for an owner to take her home and get her running again.
As you can see, this Continental is really clean. Somebody just took off the air cleaner to poke around in the carb but left it alone for one of the other 4 barrels on the lot, presumably the pickups near it. Inside it's the same story- virtually untouched. The other missing piece I see are the headlight covers. Shame, because it would look badass with them.
Also, this Continental is a 70-72 judging by the front bumper. In 1973, the Federal Government introduced new crash regulations calling for energy absorbing bumpers. This means it also has the full emissions unrestricted use of its mammoth 460 cubic inch Ford 385 big block mated to that super smooth 3 speed automatic. I would've taken her home if I didn't already have the 55 Bel Air.
