After test driving a 2006 GS300 ( I currently own a 2001 GS300 ) I noticed a slight 'ticking' sound from the engine. Most notably from under the car.
The mechanic tried to sell me that it was from the fuel injector, that it is larger because they added horsepower and therefore made this noise.
Doesn't sound reasonable to me.
Also, I didn't see any navigation feature on the in-dash screen. Is the nav functionality something that can be added?
Thanks for any help/advice.
