The reason that Lexus has retained its quality and individuality, is cause it hasn't and won't ever enter the fleet market, cause they are too dear to run. BMW/Mercedes made this mistake and their 'marque' as an individuals car went with it. A diesel Lexus? No, no, no..........
A friend of mine tried to lease a Lexus IS200 with the bank, and it was excruciatingly expensive, compared to the BMW
Thats why the Lexus marque stands for quality.....
