Hi all, I am just on the process of buying an RX 300, my first Lexus ever, and I am really excited, but one of the questions that came to my mind was, How much will I spend on maintenance and services every year? The one I'm buying's got 32K miles on the clock, does anyone know when the "BIG" service is and how much would the 40K/50K/60K services cost? Also, I have quoted an insurance for 1K, does that sounds reasonable? cheers, Antonio.
