So many questions
So little time
The fuel consumption meter is off by a bit on most that i've seen.
Reliable form of petrol calculation is fill to the brim, drive it, fill it again. Do the math of kms driven and how many litres put in.
Make sure any euro you get has the power steering hose recall done - i think thats it
The difference between facelift and pre facelift is very subtle
You wont get a good low km euro for under $10k mate
