Has same issue as most of ones I looked at, lifted from above site:
Our UK memberships provide cover for vehicles up to and including 25 years old, our European memberships cover vehicles up to and including 16 years old.
But what "cover"? When I asked them, they would not repatriate, and in the UK, it'd be a tow to local garage. The wording was a little ambiguous, hence I contacted them before (not) taking out cover.
I've lifted that from your link, rescuemycar.com 
My point is you've only have 3 more years of using the facelift for euro-jollies and no more taking the bullet.
Indeed. If/when that scenario arises, I'll probably need to shop around. But I doubt it'll be ADAC, as they were unwilling to clarify some of their T&Cs which look to be written intentionally wooly.
All that said, the cover I had when I broke down was (a freebie thrown in with the holiday) with a company that gets slated for being slow, ineffective and not willing to cover anything. Its name escapes me now. But I couldn't fault them, except the car came back with a flat battery. Our case manager handled everything once we were towed off the motorway (police have to arrange that in France), from dealing with the recovery company (to save us paying the €144 for the tow off), to relaying what the stupid French garage thought was wrong (cats!!), to finding us accommodation (it was 11pm by time we were towed off motorway), persuading garage to take us to accommodation as getting a taxi that rural would take 90 mins, dealing with the git owner, getting a taxi into Dijon the next afternoon once it had been decided it couldn't be repaired quickly, sorting a hire car, contacting the ferry company to let them know we'd miss our planned afternoon crossing and booking us on evening crossing, then rearranging for next day when it was clear we couldn't make it, to finding us accommodation in Calias when we couldn't find anything ourselves as everywhere was fully booked, to sorting out the hire car on the UK side.
All that was absolutely flawless.
My only gripes were it took a while for the car to be repatriated (few days), came back with flat battery, and the UK hire car had to be returned to Northampton on the day we picked it up, and we were both knackered.
