In no particular order...
Mazda3 -- regarded as some sort of small car jewel, but if you ignore the big wheels and tech options, it's gloomy, dreary, and overpriced
Sonata -- regarded as the car that will turn Hyundai into a serious contender, but it's plagued with mediocre quality and no attention to detail
300 -- distinctive looking and, in C/SRT-8 trims, very powerful, but it's cheap inside and insuitable as a traditional midsize family car replacement; a one-hit wonder
Solstice -- good looking, yes, but it's cheaply made and they forgot some important things... like the trunk
Odyssey -- best minivan out there, yes, but not as perfect as the reviews make it seem; awful transmission on '99-'04 models
LS460 -- lots of technology and comfort, yes, but it looks like a LWB Camry, doesn't handle, and doesn't stop
Camry -- thoroughly mediocre sedan that has nothing going for it, yet it's the best selling car in the US
RX350/400h -- luxury performance 22 MPG hybrid that's less powerful than the $10K cheaper RX350; RX -- undeserving of its best-seller title
Flying Spur -- a glorified Phaeton lacking the class of a proper Bentley, but rappers and fat boys love 'em
Escalade -- a glorified Yukon Denali with an inhospitable third row
