I will pst this here as well as the other topic this question is on:
Again, it is hard to say exactly what the price should be without seeing the car itself. I mean I can throw a price range out of $3,000 to $12,000 depending on condition, mileage, how many owners, maitenance, etc., etc., the list goes on. There are a few things to look for when trying to find out if the car is a WS6 W72 Trans Am. First the W72 engine had chrome valve covers. The regular L78 had valve covers that were painted the same as the engine. Now, aftermarket chrome valve covers are cheap and easy to install so you don't know for sure just by looking at that. The only way to tell for sure is to look at the number on the engine. If it is a YA or a YU, then it is an L78 Pontiac 400. If it is an X7 or WC, then it is the W72 Pontiac 400. Those two letter codes are found on the front passenger side of the block just below the heads.
Now for the WS6 part, again, you can't really tell for sure if the car is a WS6 without running some numbers. The first thing to look for is the WS6 stamped on the cowl tag. If that is there, then there is no guessing ... it is a WS6 Trans Am. If the code is not there (which does not mean it is not a WS6 car), then does it have the 8 inch snowflakes. Again, those are fairly easy to replace so you can't just go by looks. The other way to tell is the thickness of the sway bar. The WS6 had a larger diameter sway bar front and rear. Again, I would tell you the ticknesses, but you would really have to dig under there and take a measuring tape to really find that out as well. One way to check is the turning of the steering wheel. With the car running, turn the wheel all the way to the left until it stops. Put your finger on one spot on the steering wheel and turn the steering wheel all the way to the right..... count how many times your finger goes around...... was it 2 3/4 turns to make it all the way, or was it 3 1/4 turns to make it all the way. This one is a little better of a test because most people if they put the 8 inch snowflakes on to make it look like a WS6 car, alot of times they do not go as far to change out the steering box. Like I said before, these are just simple things to try and help determine, but the only way to know for sure is to have the build sheet or the PHS documents to the car.
Again, as far as what to tell you for a price, it is hard to say without looking at the car. I would guess that somewhere around $5,000 or less would be a good price for the car. But again, it all depends on how bad everything is on the car. The car might be rusted to s#^* underneath like the floor pans or trunk, then engine might be leaking and smoking all over in which case I would onl pay $1,000 for it. Sorry I can't help out any more than that.
