Dave, my GDI has done a similar mileage to yours. I change oil and filter every year, technically it doesn't need it on mileage but I like to know its done. In the first year I have changed g/box and diff (LSD) oils, checked plugs and cleaned the air filter. Levels are checked and suspension and prop (not too often)greased regularly.
I also do a visual, spanner and fittings check almost on an ongoing basis, even things like side screen bracket screws come loose.
I have also adjusted front hubs after initial running in they had some slack. Brake fluid I think i'll do year 2 too.
