I had some mechanics come out and fix some things on my 99 gs300 recently.

They replaced the timing belt, and water pump

new vvti seal
cam seal
sway bars

Total :

$850

They came to my house and it only took 2-3 hrs

Now I just wish the insurance company of the guy that backed into the front passenger fender and bumper would hurry up and resolve the issue and get my ride fixed (just cosmetic, but who wants a jacked up GS?) .
