Car safety letters: vehicle return within Europe without if and but?

Hi, not Caddy specific…but maybe you know some advice: I’m about to buy a used caddy. I buy from the dealer and thus have warranty. With the caddy I want to go on vacation to Croatia soon…but there is the following hypothetical problem: In case of a breakdown, the ADAC will only bring the car to my home if the damage cannot be repaired locally within 3 days and it also does not have an economic impact. Of course I wouldn’t let the holiday be missed by repairing or repairing small things. But what about a major damage, which is covered by warranty, but an economic total damage abroad or a very expensive one, which is more repairable within 3 days? Are there insurances or foreign protection letters that transport the vehicle back in such cases…i.e. in case of defect without clauses? Of course I would have for such a total damage. I could not find an offer the way I need it. thank you mazel
