It's very easy to use, with no sluggishness when starting at traffic lights, and enough power for uphill driving. Fuel consumption is well controlled, around 8 liters per 100 km in the city, and it's smoother than some dual-clutch transmissions. I think its biggest advantage is that it's not fussy, and experienced drivers say it's a transmission with Japanese heritage, simple to maintain, and durable as long as you don't drive aggressively. If you're considering a used X40, I suggest test driving it to check if the transmission has any abnormal noises. Overall, it's very friendly for the average driver.
