My first car was an 06 eclipse gt, It was a fun car and definitely great to learn on. Not to mention the GT pulls out a 0-60 in 6 sec. (I had full bolt ons/brembo brake kit etc)
I then traded it for an s2000 and what a night and day difference.

If you go from your auto gs to a manual frs I can guarantee that you won't be disappointed, just make sure you learn how to handle a RWD before doing any spirited driving.
