It is definitely practical! In my opinion Porsche's are the most practical sports cars made. You have two trunks that can fit your golf clubs, and with the RTS you can going skiing, surfing, biking, etc.
It can be an awesome convertible, it can be a truck (to an extent; with the RTS), and it can be a coupe (with a hardtop). In my opinion it is the most versatile, and all around best car made!
