Well you'll be trading in a depreciating beast for something incredibly reliable, holds value well and a joy to drive. Brakes and tires are high performance, expect to pay up for these. Not much else to expect with this car, it's bullet proof. Not many mods available for the IS-F, but it has more than enough power. I moved on from an IS-F to an S5 and then to an R8 but I still miss it very much.Hey folks, I have a 2006 CTS-V that I will be getting rid of in the future and I'm wanting to know some info on what you guys here think about the isf. I'm mainly looking for any known problem areas or anything I should be aware of. I'm looking for a 2008 or preferably a 2009 IS F. Not sure about price range, just something with relatively low miles.
