As I was washing the car yesterday, I wondered if there were any interior or exterior differences in 04-06 LS430s. I don't think there were any aside from certain color combinations that were available in 04 weren't available in 06 (and maybe 05). I'm used to domestic cars where there is usually some change every year. I remember on Cadillacs where one year the only visible difference was changing the logo on the wheels from monotone to color.

 

2004 Lexus LS: Lexus' flagship sedan retains a 4.3-liter V8, but swaps a 5-speed automatic transmission with a 6-speed with manual shift gate. Suspension, steering, and ABS systems are also revised. Driver and front-passenger knee airbags were added as were a tire-pressure monitor, steering-linked headlights, and a power rear sunshade. New options included heated/cooled rear seats, keyless access and starting, satellite radio, and a rearview camera that uses the navigation system's screen to display a image of the area directly behind the car when backing up. Front and rear styling were also revised slightly.

2005 Lexus LS: An assistance and concierge service is no longer available on Lexus' LS 430 for 2005. A firmer Euro-Tuned Suspension option substitutes 18-inch wheels for the standard 17s. Gone is the optional Lexus Link service, which provided assistance through GM's OnStar network.

2006 Lexus LS: No changes of note for the LS 430 in 2006.

Taken from Consumer guide

 

05s and 06s had the nice 18in 5 spokes as options. Like the consumer guide says, there weren't really many changes other than that.

 

What changes were made to the suspension and steering?

 

Visually, the '04-'06 were identical. The 5-spoke 18" wheels were available in '04 as well, so that won't tell anything either.

 

I didn't know that, I stand corrected. Learn something new on here everyday

 

the Euro tuned suspension and chromed 18" wheels were available on the 04's, too.

I've seen another Flint 04 Euro susp & Modern Lux, same as ours.
