i had a lexus 430 now i have a bmw 745 - the bmw was more expensive and i like the lexus sooooooo much better! in the lexus the ride is smoother and more quiet and the service from lexus was much better than the service from bmw, but that could just be the individual dealers???
If You want 2 know which one is considered the best take each one thats in the same class say Lexus LS460L MB S class, compatible Audi, Jaguar,BMW and see which one has the lowest anticipated depreciation of a 4 yr lease...My guess Lexus by a nose of Mercedes
