what's a good price for a starter
 

I have a 99' Gs 400......The lexus deal wants to charge me 350 for the starter, and 65 dollars per hour for labor.....Is that a good price?

is there the option of rebuilding your existing starter? my mechanic did that with mine but i don't have the receipts in front of me... but it was much cheaper than getting a rebuilt or new one at the time.

Thats steep. Lexus sugggested price is around $280.
Order it yourself and just pay for labor.

I've seen the starter new for $194 on www.parts.com.
