I bought the Ex35 when my son was 6 years old. Coming from Honda 2002 CRV when we was born until 2 , to 2005 Honda Pilot at age 2 to 6 . Got a 2008 Rav4 for 6 months still he was 6 years old. I saw a 0% financing for the Ex35 in which that time, the car was not selling well and there was 5-8K dollars incentive in addition to the zero percent. Trade in my 6 months old RAV4 sports V6 that i had finance at 6.7%. Upside down by 8K on the trade in, but got the 8k Infiniti incentive plus the 0% financing. I was just paying $50 more for the EX35 from my original Toyota payments. It was a no brainer and I never looked back. The Ex35 is night and day difference from the previous cars I mentioned.
I know car is not an investment and it is a money pit, but the 2 Honda cars were just leased.
My son just turned 11 years old now at 5 feet , 89Ibs. He never complained about the legroom from 6 years old to 11. I heard the 2008 Ex35 rear legroom is thighter than the new ones? Mine is an 08, but works out! I also forgot that my wife is petite at 5'3" 109-110 Ibs.
I also found out that the service pricing from my local Nissan dealer vs my local Infiniti service dept. are the same. I did ask the price for oil change, tranny flash, rear diff flash etc. all the same except, you'll find more grumpy people working in the Nissan service dept than the Infiniti. And you also have better service lounge and free car (EX35,37, G37 etc.) to use if you decided not to wait, while servicing your car. That ease of service in the Infiniti is what you paid extra with the Infiniti, and the 1 year extra road side assistance vs Nissan. Ease of service with Infiniti is priceless in my opinion for paying an extra grand or 2.
I highly recommend test driving a Certified used EX35 ( $23-28k) certified means extended warranty up to 70-100k miles included. With the EX35 you have 2 car in one The EX35 hatch gives you more room to put stuff in, specially if you lower the larger rear seat and the sedan gives you the thrill of driving vs the Murano.
Kingfrog made a good point and he just bought his Ex35 recently.
