I guess the question is, if you maintain your own car, get the v6. if you'd rather have someone fix it for you and pay for it, get the v8.
Not sure I understand your point. I fix and maintain all my vehicles. Why would I want the V6 over the V8? My decision between the two had nothing to do with the maintenance required.
Now if it was the decision between another brand and a Toyota, I'd much rather not have to perform any repairs, and only need predictable easy maintenance, which is what led me to Toyota
