Need documentation that 86 was first year for 145 speedo...

well as several of you know, i just bought an 85 IROC that supposedly has 1364 miles on it. however things are starting to get a little bit fishy. First is the interior, the seats that are in it, were not available in 85, and second, it has a 145 MPH speedo, which wasnt available till late 86'. the title says 15000 miles is the correct mileage. it was titled in 1990. I am strongly considering turning the guy i bought it from in for odometer fraud, but i need to get my facts straight. We all know that the 145 speedo came out in 86, but what i need, is some form of documented proof, so i can start putting a case together. It needs to be something from GM, anything, as long as it is in clear writing, and from GM will do. The info on this page alone will not hold up in court, so i need something better. Can someone help me out please??? thanks to all...

Well as far as the speedometer, you might start with the Federal Register... for quite a few years, it was US law that speedometers could not indicate anything above 85 MPH. All you have to do is find out when that law was repealed.

Exactly what are you going to accomplish by doing this? Get him to give you some money back because you think you paid too much, or what? What do the parts of the car that get wear from usage look like? There's a big difference in the look of the brake pedal, the seats, the place in the carpet where the right foot goes, the steering wheel, the condition of the front end parts, etc. etc. etc. between 1500 miles and 101,500 miles. You didn't really get taken that bad, did you?

I am not sure on the law but, if the two tpi 85 T/As were original than the 85 tpi cars could have had them. also on my freinds 88 gta the back said (88 firebird) this was part of the wire papper. where you install the bulbs

The federal law was repealed in 1985, allowing use of speedometers reading above 85 starting for the 1986 model year. That law is definitely something you want to find.

I guess those 85 guys changed them. I would have too but, would have kept the original and wrote the corrected milage on the drivers door jam.

RB83,
It not that i feel taken at all. I only paid 800 bucks for the car, which to me is a steal for the condition it's in. What irritates me is that he might have lied to me. I cant stand liars, they **** me off to no end, and i strongly feel that if he is lying, some action should be taken. How would you feel if you were in this situation? I dont pan to see any repayment out of this and could care less about the money. I just dont think it should go unpunished.

As for the condition of the car, the front clip is not original, and it has been prepped for paint, so the original condition is unknown at this point. there is no brake pedal, so that can't be factored either. The carpet looks brand new, and i think it might be. It's not faded, worn or anything. the seats are also not original so they cant be factored either. the original tires are still mounted on the car, and while they definatley dont have 100000 miles on them, they appear to have quite a bit more wear than would be caused by 1300 miles.

This whole situation is still very sketchy. a large part of me believes that this car really does have 1300 miles on it. the steering wheel, turn signal lever, fog light and defrost switches look brand new. the underside of the car is in immaculate condition. it even has the original Bilstien shocks in the back.

Finding proof of the speedo is just one step i plan on taking in proving myself. i haven't even convinced myself yet, and i won't turn anyone in until i am 100% positive that he is lying to me, which i currently am not.

Im going to look into this repeal on the speed law, but dependent on the exact date it was repealed, it may not be applicable. If it was repealed before my car was built, it may be argued, that the speedo could have been put there by the factory.

thanks for everyones input so far...

How about a copy of the press release for the 1987 model year. That will have ALL the changes for 87 and will probably list the 'new' for 1987 145mph speedo.

BTW-My friends 86 Z28, non TPI has a 145mph speedo, I am assuming it is origional as nothind else was modded on the car when he bought it. Is this possible. It had 92,000 miles on it when he bought it, so I dont think it was changed.

His is dark blue, LG4, but 5-Speed. If I give you the VIN, what can you tell me about it from your archives?

Check the archives. Somewhere on this board I found the following information about Camaro speedos:
1985: All 85 mph
1986: 85 mph on all Camaros, except late year Z28s with TPI, which had 145 mph.
1987: 145 mph on Z28s/IROCS with TPI, both 305s and 350s.
1988/89: 145 mph on IROCs with TPI, both 305s and 350s.

The difference between 305 and 350 cluster is the tach's redline, one, I BELIEVE, at 5, the other at 55.

Consider this: How many cars with over 100,000 miles have you seen that still have the original battery, alternator, starter, water pump, hoses, belts? What's the condition of the seat belts. A cat with over 100,000 will definatly register higher emissions than one with only 15000.
The Windshield will have so pitting etc... these are just a few items I look at
Last, I did consourse restorations awhile back and a dead give away is rubber washers in door panels, under locks etc...the difference between 15000 and 100,000 is clear.

First off all didnt you the car was a recovered theft?, if so , someone may have started replacing parst that where taken off , ex. seats , as for the speedo ,, it might have been a typo when it was registered ,, i know i always guestimate when i title a car i know what it has i never put down the exact mileage hell i cant remeber it have the time , also if it is the original dash. do you know when it was built , GM was famous for installing oppions before they where supposed to availible , if the car was a late model year it might have recived the new option dash cluster for 86 , being that it is an iroc . So i dont know if you want to go after this guy , especialy if its a recovered theft. totaly different set of rules

Oh i think im definately gonna go after this guy. i just ran the VIN through Carfax and it says that no title exists for that VIN. Im goin to the DMV tomoroww to try to retitle it in DE, and if it comes up like it did on Carfax, i'm gettin a lawyer.

BTW the car was built in 7/85, which is a good year before the 145 speedos. As for the seats, since it was a theft recovery, thats understandable (although he might have lied to me about that too). I guess we'll see tomarrow.

So in all, Im having a really bad day. On top of this car, i just found out my rear main seal on the 86 is going bad, so i gotta fix that too... THIS SUCKS
