I have a 2006 GS300 with 128K miles. Have owned it since 8K miles. It's been (and continues to be) a great car with no unusual problems.

So far, I have done the standard 5/10/15/30 services, repeated of course throughout the life of the car. In addition, I had the spark plugs replaced at the last service. I went back through my records and don't see any replacements of the timing belt or water pump. I live in Phoenix, Arizona, so the car is primarily in mild to hot weather.

While I don't want to spend money needlessly, I want to keep the car running well and understand the need for preventative maintenance.

What maintenance do you recommend for a higher mileage 2006 GS300 to keep it in good shape?

Transmission service and Timing belt/WP...for sure

Don't think 2006+ GS3 have timing belts but the drive belts and water pump/ t-stat are a good start, also getting brakes flushed and rear diff fluid changed

Doh!!! You are right...I don't know why I assumed 430 and not 300...no timing belt

I only did the regular oil change and spark plugs, I've never flushed any of those things and it ran like a champ at 320,000 + km on my first 3GS.
