I basically bought my Lexus because I wanted one since I first saw them. My 1996 Ford Explorer was dying, and after test-driving (for the first time) an RX300, I fell in love.
It's a 2002 RX300 with 50k miles (just turned). I bought it used with 44k about 6 months ago. It's phenomenal. I test drove the vehicle at night, and after turning the car on and having the HID lights automatically come on and level, i was hooked. I know it's not exactly a feature exclusive to Lexus cars, but the brand, the smoothness of the ride, and the size of the vehicle really won me over.
I couldn't be happier.
Not to mention, when I drive friends around at night, not only do I get compliments on my headlights, but the luminescent dashboard is a real tourist attraction. :)
