This RX is my wife's but I drive it on trips or when we are both in the car. Purchased ours in Nov 2008 with 35K miles. Had the condensation in right headlight when we bought it. While outside warranty, Lexus agreed to replace it and I paid $500 off $1800 bill!!!!!
Radiator leaked. I replaced it myself but found out lexus had extended warranty that would have replaced it free. The same side hedalight had condensation again. Fixed it this time by applying silicone around the lens. It has worked perfectly. Very comfortable seats/driving position on long trips, quiet, roomy. It has aged very well. leather in seating area is top notch.
Currently at 95K miles and ready to sell it.
Very reliable, smooth, and quiet. Built well. well equipped. Good highway vehicle. Drove exceptionally well in one bad snow and icy weather trip. Best choice tire (not cheap) is Bridgstone Dueler Alenza. They have gone
60K miles so far and still good.
Engine, transmission, brakes hold up well. So has the paint and body panels. it is 9 years old and there is no rust anywhere and we live in a snow belt state.
I did not like the timing belt expense of $580 at 90K miles.
The 3.5L in RX350 uses chain so that won't be an expense in our 2010 RX350.
The gas tank capacity says 19.5 gallon.
I could never ever put more than 17.5 gallons in it no matter how dry it was.
I honestly can not ask for any improvement change in this 2004 RX. I really think the 2004-2009 have much compact and nimble feel to them than the 2010-2013 style. The new ones look and feel bulky. Shutting the doors is not as mooth as the ones in older generation. The older 330 used regular gas, the 350 used premium tthat could add up when owning these for 5-7 years.
