Took a Limited I4 for a spin on friday. One thing that bothered me was that the back seat was noticeably louder than the fronts seats. The fiance was driving at first, and I thought it was slightly noisy, once I was in the front seat driving it was much quieter. Do you RAV4 owners notice this? Wondering if it's noise from the differential or motor. I'd imagine if it was engine noise it'd be reverse.
