We have a 53 Rav 4 , the 2.0 petrol. We have owned it for 3 years and found it to be a good solid car and not had any mechanical problems (or any infact!) with it. Very reliable, relatively cheap to run and insure, however the 2.0l is a bit gutless and as such drinks a fair bit of fuel. A tank of fuel is about £50 (approx).
Boot is big enough for most things (bikes, dogs, shopping) and you can slide the back seats forward to make the boot bigger. The seats also fold into numerous positions. All in all, quite spacious, nice to drive and well equiped. Would have preferred a diesel but we dont do the mileage to warrant it. Looked at the X-Trail too but preferred this. Having driven and used an X-Trail since I still prefer the Rav.
