The fellow who asked the original question (are RX's for old people and/or women?) may be missing a big point: Half of the population are women and people over 40. Most 20 - 40 year old males cannot afford a LUXURY vehicle of any type, but for those who can, they generally buy whatever floats their boat. Everybody has their own criteria, and the choices are many. The "macho" look is but one criteria.
I bought my '04 RX330 for several reasons. First, because , at age 59 (yes, I'm an "old" guy) I have knee problems, the higher seats make getting in and out easier than a sedan. Much easier. Second, at my age, I can now comfortably afford to buy a $50K vehicle. Third, it gets me where I want to go in comfort, is inexpensive to operate and maintain, and fits in respectably with the Mercedes, BMWs, and other Lexus models at the county club. I can pretty much afford to buy whatever vehicle I want, which is what I did.
