Disappointing reliability. I had to replace the transmission (failed solenoid pump) at 150k mi. You have the option of "rebuilding" or "replacing". Lexus wanted $3400 for this, I rebuilt it for a hefty $2600. The "new" 99 tranny is twice as expensive to fix as a 99 Camry due computer chips in the transmission. All 4 struts needed replacing at 150k mi as well. The "check engine" light has proven quite annoying as it appears a few times/yr due to a fuel system anomaly. This automatically disables the Traction control system and a dummy light appears for it as well. 21-23 mpg as I would guess this is standard for a 3 ltr V6. Poor turn radius. Disappointing reliability overall.
Drives very smooth, Great stereo system, quiet ride. The 99 Camry XLE V6 is a much better buy for the $$ especially when it comes to repairs and to the untrained eye it's an exact replica of the ES 300. Average person will not have these problems w/ their Lexus, mine happened to be problematic.
Tighter turn radius, 5 speed transmission (I'm at 2500 rpm at 70 mph, this should be 2100 rpm at the most and would help with fuel economy at hwy speeds). When I replaced my transmission it was an option to put in the 5 speed for $3500!! It would have required an all new computer system to integrate.
