I bought my wifes white '99 ES300 in 2003 for $17,500 with 69,000 or so on it. At the time I thought it was too much, but later figured it was a pretty good deal.
As a matter of fact, I liked the car so much that in July '06, when I was shopping for a new GTO, I ran into a friend whose mother had died and wanted to sell her '01 ES300 for $14,000. Out of curiousity I went to look at it and it only had 37K miles, records of all maintenance, and brand new tires. Even though it hasn't been washed in a few months it was pretty much spotless. I ran down to the bank and bought it.
Since then I bought 17 in. ADR rims, tinted the windows, and installed a wing on back. The brand new 16 in. tires off it when on to my wifes new "Bling!" rims (I'm not a chrome fanatic).
