I found this review of the IS250. IS250 Road Test
They compared it against the BMW 3 and Audi A4. extract->"On the inside fit and finish are good too but the perceivable quality isn't quite yet on par with that of the Audi A4, which we regard has one of the best interiors.Furthermore the interior appears still a bit "Japanese" and are there one or two elements, such as the digital clock, which reminds of its Toyota genes. The flashy plastic centre console is also a bit too much for our liking." ....................."It definitely isn't dull either thanks to its eye-catching design. But it isn't quite able to match the driving experience of the Audi A4 or BMW 3 Series."
I must say i dont agree with it. In my opinion the IS has better quality interior than the A4 or the BMW 3 series. The Audi A4 is a front wheel drive car it is strange that it is compared with the IS. Would you agree to the review?
