I am currently looking at family SUVs under $8k. Safety, efficiency, and reliability is what I am looking for. XC90 came on my radar, a couple of them, and I need help choosing. Option #1: 2006 Volvo XC90 V8 AWD. Has 156k miles on it. Below $6k. 3rd row and most bells and whistles are there. Seems like a heck of a deal for a reliable SUV with V8 from Yamaha and robust transmission from Aisin. But... there is option 2: 2006 Volvo XC90 AWD 2.5T. Same vehicle, similar price, different drivetrain/powertrain, and has 98k miles. This 5 cylinder has been around since 1990s and is proven to last. If I get it - PCV system and timing belt are getting changed right away. I am now torn between these two. I want the power of a V8, but the 5-banger has less miles and is just as reliable, AFAIK. Help me choose if you had close experience with either or both. What other issues are common with these cars? Thank you in advance.
