Hold on. Hold on.
You got a GS430 with a 6 speed
manual?
Car and Driver mentions nothing of a manual. Neither does
Lexus' very own homepage.
Unless of course, you meant that it's one of those hydraulically controlled clutch pieces of crap. In my world, a manual transmission means there's three pedals down in that footwell. Anything less is an automatic.
Nice car to treat yourself with! For that class though, my personal tastes lie within Infiniti's bitchn' new M45.
