Hello, I have a 2010 Honda CRV EXL 4WD which was made in Japan (vin number starts with J). I noticed a huge difference in the way it accelerates compared to the ones made in the US which I test drove on the car lot before I bought mine. Is there something to this? The difference is that the one I have is so much more quiet compared to the US ones which are much more loud revving. Any ideas? Thanks so much, Jill :)
