well to be fair 144lb of torque isnt much but it works well in the design of the car, the is200 is a comfortable cruiser which i could never fault, and his has the power through out the rev range i find even in 6th gear to put the foot down and over take happily on motorways or any other situations, power is there in the car just not flat out acceleration or speed but as i said, car wasnt built to be a balls out speed machine, its a business mans or family luxurious vehicle, it does its job well through out its life whether it be 50k miles or 130k miles,
I have an IS200 sport with just under 120k miles and i've driven a car similar to mine with less than 60k miles and didnt notice any different, I couldnt fault my IS in anyway, regular services and change the worn brakes bushes etc like you should do on all cars and it stays like new, very reliable,
want a fast car, buy an mr2 or an evo etc, want something with enough power to keep you going for a long time and in comfort to give you the driving pleasure forever then buy an IS,
I dont think i could change my IS for anything, looked at jags bmw merc audi etc and none of them felt anywhere near as comfortable or solid as my lex,
so i disagree that it is underpowered, i beleive it is a perfectly balanced car and does its duty proud!
