No, I'm saying that the 1999 COUPE was an E36 - since bmw didn't make the E46 coupe till 2000. The 1999 FOUR DOUR SEDANS were E46's.
As for the same reason 1992 325i's were E36's, and 1992 325ic (convertible's) were E30's.
Here's the FACTS. In the USA;
E36 328i COUPES were built until April, 1999.
E36 sedans were built until April, 1998.
E46 323Ci (COUPE) was built starting in 11/1998
E46 328i COUPES were started in 11/1998.
Confusing, eh?
