This my second very used GS300. Purchased at 238000 miles knowing the platform was not badly treated but needing brakes and ball joints but not much else. I have 324000 miles on it now and just replaced the brakes again along with a new radiator and suspension parts like links and bushing assemblies. Quiet, tight and smooth steering all back and it is a dream to drive. My normal driving yields about 20mpg stretching out to about 27mpg on a trip which is great for such a heavy car. The very smooth motor is phenomenal in its performance and reliability and never failed to start hot or cold. Sure, there are things failing like my remote door locks and one now started locking when I put the car in gear, and there is something in the rear trunk key hole jammed in it making the remote lock or the dashboard button the only way into the trunk. My value perceived for this vehicle is great seeing I paid $1800 bucks for it and just did repairs to it. I have had it over 8years and do not intend to sell it. The only detriment and strength is the rear wheel drive which is a little tough in New England snow conditions but yields superb handling without the torque steering of front wheel drive. It is a dream to drive.

Bought 1999 GS 300 at 90k in WA in '06, now at 302k in '22 in MA. Other than the standard timing belt water pump services every 90k its the most reliable comfortable car w power I have ever driven, even w friends cars. Mechanics told me its one of the best out there w that legendary engine. Compression still at 175-180 (dry) which I read is near its original. Have been replacing coils, gaskets, struts, tie rods, O2 sensors, 1 front wheel bearing, front calipers, belt tensioner, crank pulley, last 3 yrs. Nice to have a mechanic for brother in law. He was so impressed w mechanical design he bought a used lexus IS for his daughters. Another mechanic says he has seen them go to 500k in FL. They noted the transmission is very tough. No issues there either w regular fluid changes. Maybe only MA road salt will eventually kill it, but I am stopping that for now underneath, not much so far after 4 yrs here. Read only 0.7% of vehicles make it to 300k, mostly Toyota SUVs. Valve seals probably need replacement eventually but w additives to oil, that is not an issue either. Lexus dealer here says I have the only one they know of here & ask all the time when I will replace it. Maybe after 400k ? Will see.

This car went the fastest that I have ever driven in a car, and it was smooth the whole way through. Fuel efficient for a luxury straight-6. It was very comfortable. That engine is the JZ model that they put in Toyota Supras. I gave up on mine at 174k miles with front suspension issues and an oil leak.
