NOTHING.
This SUV is fantastic.
The feeling is like you drive a GTI.
I do not like the acceleration.
The 15.000 km service (full synthetic oil, filters etc) cost me 110 euro.
I drive the RAV in snow without problems.
If you want a car for sity 30% trips 50% snow or sea 20%, rav4 is the best choose.
(in the past I was owner: jeep renegade, geep cherokee 2.5, daihatsu feroza 1.6, kia sportage 1.6)
DO NOT FORGET THE RAV4 IS NOT FOR HARD USE 4X4.
More details
1) engine noise after 150km/h
2) current 8,5L/100km
3) top speed (easy) 200km/h (tested with gps garmin)
