Biite um (technique)tips for 6000km travel

Hello everyone! For three months I have had a V70 2.4T, MY 2001, Automatic, Premium and am completely satisfied. At the same time I read here in the forum and I am happy about the increase in knowledge and the nice contributions. Now I thought I could use the accumulated knowledge of the forum members: We want to next spring possibly with the elk from Berlin to Portugal, have 3 months time (parent time….) and want to make various stopovers with friends in D, F and ES, therefore the idea to drive with the elk. My question: What should I take with me (for the car)? The car is actually check booklet maintained, has new tires, the brakes incl. disks have to be made and I want to have them made before. Bin ADAC Plus member, because the starter has already gone out last month (and I stood with the automatic in Brandenburg….). A thousand thanks in advance for all tips and suggestions, the forum here really great (have already placed the “clapping” door panels quiet after instruction). Best greetings, Mark
