I was interested in finding out some of the differences between model years of the GS430.

Did all 3rd Generation GS430 have keyless entry?
Is there a certain model year that is more refined and stands out?

Thanks

 

Yes, and depends on what you would consider as "stands out".
Apart from the '08 facelift, with integrated LED turn signals in the door mirror and front wing's removed, chrome surround on grille/front bumper design, and round buttons on steering wheel for audio mode and voice activation control, there wasn't a whole lot of difference between the two versions.

I suppose the door mirror change was the most obvious in terms of bringing it more up to date, the rest was just industry standard mid-production cycle styling tweaks to help boost/maintain sales.

The main difference worth noting is the facelift introduced the 460 model with engine capacity up and switch to chain rather than cambelt driven.
Gearbox got 8 cogs - 2 more than the 430/350/300 have.

Also just remembered, hopefully correctly, the font used on the gauges is slightly different - think the facelift went with an italicised style, but it's very subtle.
You'd probably never have known if it wasn't pointed out to you.

 

Thanks for the info, I'll stick with the 430.
Is the engine ECU the same in each year, or were there changes?
Curious, are there paddle shifters in the 3rd Gen GS430?

 

No paddle shifters in the 430 or any GS models, 430 only came in one year 2006.
