I currently own a 2010 Mazda 3 GS Sedan, and unfortunately I can't help but wonder if I made the right decision. For a fraction of what I paid I could have got a 2004 RX-8. I just wanted to get some opinions on whether I should have gone with the RX-8 and how the RX-8 compares to the Mazda 3. I'm thinking about trading in or selling my 3 privately while it still has low KM and getting back as much as I can. Thoughts?
