Well I will be the first to give the bad news.... Eclipse GS will win... I had an 06 GS before the 08 GTS and even tho it was standard it had a lot more balls then the GTS does... 155hp 2.0L (GTS) vs the 165 2.4L (GS). No to mention I think the eclipse was a tad lighter and geared better...
i woop my bros 2.4 gs in the frwy...we bought our cars the same day too and tried it out...in my say my lancer is far better than his eclipse in very way...
