I'll just get right to it. So I'm looking at buying another Camaro. It's listed as an 88 RS. I'm in Canada and noticed the RS was only available in select states. So I've been trying to do some homework to determine if it is indeed an RS, or just a sport coupe or maybe even something more (I noticed a Z28 rpo). I went to GM and had them email me the rpo list for that car. So here it is. Any help and insight is appreciated.

Doesn't look like a RS.

Looks like a fairly typically optioned Z28; nice enough car, but nothing extraordinary.

Ignore the ad copy. Don't argue with the owner about what it is. Don't even bother bringing up the subject. Either buy it or don't, according to whether you think what you see is worth what you'll have to pay to get it.

 

Their Were No Z28's In 1988,Only Sport Coupe's And IROC-Z's.

 

Exactly: all the Z28s got the IROC pkg for acoupla years, as described in the above RPO list; unlike earlier years where the IROC pkg had the additional RPO B4Z. I guess GM was getting their money's worth out of paying IROC to license the name.

 

So what I gather it's a Z28 (or IROC-Z28) as that's what they called them in 88?

 

Would appear that way, assuming the VIN is correct... RPO codes do not lie.

Make sure the VIN on the vehicle you are looking at - in ALL the places the VIN is stamped - matches the VIN you looked up.
