What should I check/upgrade for a 3.000km road-trip in an 2nd hand car?

Hey r/cars! I’m not quite sure if this is the appropriate place to ask this, but I thought I’d give it a go.

This summer I’ll be doing a road-trip of just over 4.000km’s trough France in a 2005 Opel/Vauxhall Corsa C 1.2 with over 220k km’s driven. This is going to be my first long (+500km per day) drive with this car and I was wondering if there are any parts/fluids that are essential to check or replace.

I bought the car in august last year, and it was then MOT approved (APK in The Netherlands). The tires (all-weather M + S Vredestein), the chassis and the engine (1.2 litre 80hp, twinport) seem to be in a good condition. I have never had significant problems with the car, except for a misfiring spark-plug once, which I replaced. Sometimes however, the engine hesitates when accelerating between 2k and 3,5k revs. I have not yet found the problem so that’s why I plan on replacing al of the spark-plugs. Next to that I plan on replacing the oil, the coolant and having the brakes checked by a mechanic.

Am I overlooking something?

Are there any aspects of the car I should inspect as well?

Thanks in advance!

EDIT: The 3.000km in the title should be 4.000km ​
