warranty data. Toyota decided that they wanted to be the biggest car company in the world and sacraficed their quality system to do it. I own a TDI and while I like the MPG it isn't what I would call a Nice car it is kinda low end but it is good for dumping a lot of miles on it. It will go 300,000 - 400,000 miles. You probably won't get that out of an IC engine. Honda Powertrain is very reliable.
This is just my educated opinion.
