I have an 07 is 350, now im shopping for an isf..looking at 08 to 10, the few I have seen don't have A/C seats, does any even come with this option??...or rear shade??? and is there anything major that is a problem I shoul watch out for??? thanks

ISFs don't have A/C seats or rear shade, unfortunately.

The only thing to watch out for is the extra RWHP u are about to experience...

Seriously these are great cars and if you find a 08-10 in good shape u will be happy as they are very reliable and fast! Yeah the ISF only comes with heated seats...sorry

Good luck with your hunt and hopefully u will be a member of the ISF club soon

ISF' are meant to be driven, not to be pampered in. If I could, I wouldn't even have the moonroof, which is pretty rare to find unless ordered that way.

LOL...thanks guys, I test drove one today( now im hooked) just the one I drove wasn't really well cared for( what a shame)....and what is the MPG on the HWY that everyone is getting

Just over 24 at 80mph. :/ Yeah, I wish we had cooled seats...

28-31mpg going 70-80mph with occasional squirt.

wow...not too bad, why is some of the ISF I see have gold brake calipers , some have blue, but (MOST) have black???....Im sorry if these seem like stupid pointless questions, but im still shopping

^ brake calipers come black standard, and whatever color other than black would have been sprayed afterwards.

My 2cents one
Over 350hp used car
And this case isf
1st its a good choice that u will actually feel th big different between 350 n isf the power
But when u look for 08 n 10
Has the have any mod ? Exhaust or intake is fine in my book
But nos or header is something. U should check for
And if the car was oem all the way from day one good
But if the car has a mod or its been moded make sure what mod were on and who made back to oem and why
If dealer made that to the oem from modified something fish about the car
If the car comes as is or whatever
Check n confirm from the dealer about the o2 censor n spark plugs r in good condition cos thoese thing cost
N break rotor n pad life check because isf break job is more than is350s

if you can get the 2011 there was quite a bit of changes. Or you can get an 2010 (gets LSD) and find someones 2011 suspension takeoff since 2011 got the big suspension update

well I got an 08 ISF, pretty good shape..... but after a week of driving these breaks do dust a good bit, any suggestions for some pads( when it comes time to replace) I should get that don't dust so bad?
