This seems to be about as fair a comparo as I can come up with. The TMV price is about $34K for the Infinity G35Journey w/ premium package and $34,800 for the base IS 350. This is a fairer comparo than the IS250 as that's outgunned by the high HP G35. Both vehicles have the 300+HP V6s, sunroofs, and power seats. The G35 has the premium stereo, xenons, & memory seats. The IS has a more refined interior fit & finish(from what I've read, haven't seen it in person), a slightly better resale, and unlimited roadside assistance. Would really like to hear from those that have done a side by side comparo as I'm really leaning toward the G35 thus far.
