Dealers would do about anything to a car to sell it! I remember when the 1982 Mustangs first came out the automotive press went crazy - probably because Ford had a huge marketing budget!
There had been a serious lack of power in Mustangs since 1972. The '82 GT was placed on the front of a magazine that read, "The BOSS is BACK". We bought one of the first GT's in OKC. The dealer soon put a decal package on the cars that placed Boss 302 stickers in different configurations on the cars. Luckily ours was 100% stock. Very fun and balanced little cars for their day!!!!!
These pics show a car just like ours. BTW it was my sister's car but I drove it about a month when it was new to 'check it out' and make sure it didn't need anything!
