5: BMW Z3 Coupe
BMW is a brand that hit its stride in the ’90s. The BMW lineup from that decade is considered one of the best lineups in the history of the company. The Z3 Coupe is one of the most unique looking sports cars that came out. A hatchback design was incorporated with the standard design of the Z3 (via Consumer Reports).
A relatively low production run made the Z3 coupe unique. There were no compact luxury sports coupes during this time, and the Z3 was an innovator. BMW was known for pushing the envelope of design around this time. Few cars are as notoriously rare as the Z3 Coupe is from this unique decade.
