Sportdesign all the way. Black Pearl emblems, trunk lip spoiler, wood shift **** & ashtray, Sportdesign mats & door sills, different headlights, saddle leather...

Get the Sportdesign, you wont regret it. I love mine...

The only factor I kinda don't like about SportDesign is the engine...it's only available in GS300 form. But then again, we all know 2JZGE can be forced inductioned A LOT easier than GS400!

SD is a great combo, the saddle interior is very unique

Test drive them if you can. Try to get the "demon" out of the engine ;]

SD!!

I was actually searching for a SD with the V8, then I found out they didn't exist. For me, a V8 was a must!! (I didn't want to turbo the 300 either)

My personal opinion I think the resale value of the stock Navi would be greater than one w/ sports design or aftermarket navi. As you stated when you blue booked both cars. I've only seen pics of the saddle interior and prefer the tan interior. I had an option to pickup a GS300 sports design when I was searching for a GS but found a better value in picking up a GS430. V6 vs. V8 my choice was easy as I didn't have any plans for forced induction.
If you have no plans for forced induction you may be better off looking into a 430.
