have to remember that edmunds doesnt have the best test drivers. they ran 06 sti vs 06 evo MR and got 0-60 in 5.5 with both.Street or a race, anything could happen, so just go and race him. Most of the magazines aren't too far off, usually by a few tenths of a second if that. They do several runs with qualified or professional drivers. But, like I said, you could end all speculation by simply racing one. Good luck!
(BTW , the msn.com link of the manual running a 14.96 might have BEEN with a great pro driver, yahoo has the car pulling a 15.10 on the 1/4 time, others on the same link have it at 14.6, so just race him and find out. Click here to see it:
On edmunds from someone who actually owns the car, he ran it stock at the track and got a 14.99. You can see that here, third review down:
The Eclipses aren't bad cars, but the base price on a manual base shift GT is over $28,800, and they also weigh over 3,600 lbs. (for the base model). Check out this good review of the car as well if interested, by edmunds.com, the review of the new 07 Eclipse. They too tested the car at 14.9 in the quarter mile. This review covers everything you could/would want to know about the Eclipse from handling, to performance, to suspension. (Quote from the article: " With its large 40 foot turn radius... U-turns can take weeks!")
Allright, I have done some research for you, but again simply race one and find out, the Eclipse is a cool little car. Good luck!
