Europe has a well-developed network of autobahns
For a motorist, the main (and primary) mode of transport is the car. So put aside other matters and start preparing your car for a trip abroad. If your vehicle is a Mercedes, a service center is the first place to visit. There are plenty of reliable service stations in the city whose specialists will prepare your car for a long journey.
Make sure to get a reflective vest. Why? In case of a breakdown on the road (or any other situation), it is forbidden to step onto the roadway without it. If you are going on a trip with friends (family), this item will be necessary for them as well. Otherwise, they will have to sit in the car or get off the road onto the shoulder (away from the highway).
A radar detector is a 'gadget' that is banned in Europe. Notably, you can be fined (a substantial amount) just for having the device in the cabin. So leave it at home and try to follow the rules; you must not exceed the speed limit anyway.
Do not rely on driving intensively at night. The driver must also rest. Experienced travelers cover no more than 1300 kilometers, but only on very good autobahns. Expect to spend almost every night in a hotel. There are many hotels in European countries, but it is wiser to book rooms in advance, especially during peak tourist season.
Another problem may arise for fans of tinting car windows. In Europe, tinting of front doors and the windshield is prohibited, even very light tinting. To avoid trouble with local traffic police, it is better to remove it before the trip. This can be done when your Mercedes service is due.
A navigator will be indispensable on the trip. Do not use a similar option on your phone; the device must be on constantly, so let each device perform its own function. However, experienced motorists advise taking maps along as well. The device can fail, and it sometimes plots a strange route. So it is better to be safe. Keep in mind that maps must be up-to-date; everything changes very quickly in Europe, even though it is called 'old Europe'.
Stock up on cash; in almost all European cities, parking is paid and machines do not accept credit cards. In some countries, you will have to pay for roads as well, but there you can use a credit card.
