Well enough is enough i have chopped in my IS 250 Sport (which was a replacement for a IS 250 SEL).
I'm now the proud owner of a GS 300 SEL and what a difference - no cheap looking silver coated trim, no more fighting the gearbox, no rattles from somewhere on the passenger side.
Basically i had enough of the niggles, to the point that i did'nt 'love' the car like i should.
The GS is so much more refined and smooth to drive, it also makes the interior trim of the 250 sport seem cheap.
I have driven the GS during the open days and it always impressed me; however i was taken more with the styling of the new IS and its aggressive stance.
That said the GS has slowly grown on me and i can honestly say that after 3 days of ownership i am confident that i have made the right move.
In my opinion the GS is in a much higher league than the IS.
