It's hard for me to give a general number, but it is the best new car I've ever owned by far: no warranty issues, no defects, no squeaks (except for the center console which was my fault for ripping it out...fixed it with felt dots) smoothest ride, best mileage, most comfortable...the list goes on and on. There are a couple of petty design issues I suspect Toyota will change: folding mirrors, reading lights that go out after a period of time, Eco mode switch in a better place...little things like that, but these are minor compared to the long list of design complaints and warranty issues of my other new cars. I think I had my Honda Odessey in for warranty work at least a dozen times, and sometimes for wierd things you wouldn't expect from Honda. Here's a relative 'score' of my cars which I believe helps put it in perspective:

1991 Nissan Pick-up: 7.5
1995 Dodge Neon (it was a new model, so maybe not so bad): 8.0
2000 Honda Odessey: 6.0 (very surprising)
2007 TCH: 9.5

Judging by my buying patterns, I suspect I'll replace the Odessey with a 2011 Totota Sienna hybrid...I hope.

Not just Super White...Super Duper White...
