We got our 2008 EX35 used with around 30,000 miles and it is now approaching 100K. Only major cost has been a new radiator. It runs perfect, but we have faithfully had all the recommended maintenance done as scheduled though. There have been the standard frustrating issues like rear hatch not opening, memory seats sometimes not remembering, etc. Nothing major...knock on wood. But I'm not sure if you want to put your young daughter in a 297hp vehicle!
