Rav4 T180 - New purchase - preventative advice

[Mikeyjd]

In the process of buying a 2006 T180 (to replace my wife previous D4D which was written off). The car is quite low milage for its age 80,000, and in lovely condition with full service history etc. I'm looking for advice on keeping the car in good order and hopefully reliable. So, any suggestions for things to check or do.

I am thinking of using premium fuel most of the time, also Archoil ARG900 fuel additive. Will obviously be doing regular checks and oil changes etc. Anything else? Is it work cleaning or even blanking the EGR. (what's the latest consensus on EGRs)? Any other suggestions taken on board.

She absolutely loved her previous Rav4. Had it 3 years and it was a high miler 150,000 miles until she was T-boned. I want the replacement to give her ss much enjoyment.
