Hi, I bought from new in 2002 a IS200 Sport and then a IS300 in 2004. I part exchanged the IS300 in 2010 when i bought new my IS250 F-Sport and I can honestly say that the F-Sport feels as quick as my IS300, it handles much better on the road with a firm but cushioned ride (anyone that says the ride is choppy probably needs a wheel alignment as the cars toe settings may need adjusting) and the refinement is so much better. I'd highly recommend this car, it sits lower than the standard IS250 due to the F-Sport suspension. I have 46,000 miles on mine now and its as good as the first day I bought it! Tyre wear is great too, can't say the same for the IS200 & IS300!
