LOL, test drove a GXP solstice before I got my Abarth, not a bad car but felt cheap and felt like a pig for its size. The 124 on the other hand felt like an Elise, fell in love and financed a car for the first time since 04.
I had an 08 2.4 na. In hindsight should have got the 2.0 turbo. The car was fun to drive and often got positive comments. The top was the biggest problem. Open the trunk, pull it out, click in in place then attach two side panels. Oh yeah, you lost the trunk with the top down. It felt heavy to drive, the 124 feels nimble. The top is a dream come true. When you figure the dealer markups on the Sol, the 124 is basically the same price for much more car. I am sure this sounds strange, but I would never have got a Miata although several friends have already called this a fiatta!
Welcome to the forums and congratulations. I've always loved the Solstice especially after seeing those crazy custom builds people used to do with them. Nice to hear your comparison between the two though
