Let me start by saying I love my IS 350!! This car is amazing, everything you would find in a luxury vechile with power and performance. Many compliments from everyone I know and some I don't know. If you love to drive my suggestion is go test drive the 350 do not bother with the 250. and buy it you not be disappointed.
The keyless unlock and start is cool. Matador Red paint, THE POWER!!! The fact that I have already raced and won against 350Z, S2000, '04 corvette, '04 mustang, 330I BMW, Stock SRT-4 and more to come.
Not much room in the back seat but I guess that is why we have our RX 330 also. Memory seats should be stock. Should have xenon lights stock.
