What Toyota/Lexus Needs to Build

I know this is old n'stuff, but a recent online discussion brought it back to my memory. This is the Lexus IS430:

The MillenWorks built Lexus “IS430” was unveiled at the 2003 SEMA (Specialty Equipment Market Association) Show in Las Vegas, Nevada. Commissioned by Lexus to highlight the immense potential of the IS300 chassis, the concept is powered by an enhanced 4.3-liter V8 engine from the Lexus GS430. The V8 engine is paired with a Getrag 6-speed manual transmission and a lightweight flywheel, driving the rear wheels through a high performance limited slip differential and GS430 driveline components. MillenWorks engineers estimate that the modifications are good for 60% more horsepower at the rear wheels.

Sounds like a pretty good family hauler to me.
