Funny you mention it...I happen to collect old auto ads....though I don't have any Intrepid ads, I have ads featuring Ricardo Montalbahn hawking a 1984 Chrylser LeBaron Convertible.
Here's some of the original ads I have:
1984 Fiero
1984 Ford Tempo
1983 Buick Century
1984 Renault Alliance (only $5,959!)
1984 Lincoln Continental Mark VII
1983 Ford Thunderbird
1983 Ford Mustang Police Pursuit
Also an ad from Dodge showing all of their "Imported for Dodge" Vehicles...too funny!
I also have a load of late 50's ads for Fords, Chevy's and Chrysler vehicles...I'll get around to scanning some of the better ads and posting them.
