I try to use optimax, it seems to give the best fuel economy. Best range so far is 650km on a tank. I also have shell helix ultra (grey pack) as my oil.
I think this combination, while expensive is the best.
The front wheels seem to develop a lot of brake dust/road grime. I need to clean these on average every 2 weeks to avoid the brake squeal.
The Michelin tyres fitted are very good, however the hub caps are very difficult to remove.
Headlights are excellent. Front fog/driving lights are very costly to add. The manual doesn't describe globe sizes, these however can be found on the headlight lip cover.
The Polar Sea (Blue) paint finish seems to turn purple in the late afternoon sun, an interesting fun part.
I really like the fully adjustable steering wheel. The wheel itself is very good to hold, however the black finish shows the dirt.
Speed sensitive stereo is very enjoyable on long distance trips, and changes according to road surface. EG tarmac to concrete.
Cornering at high/low speeds is the best feeling. The feedback is very good.
