Verteter wants to give me a safetycar verse.

If these days for my three vehicles get calls from advertisers of my insurance company, they would have noticed when reviewing my contracts (net, so to make the contract-related reason of the call, otherwise it would be illegal telephone advertising) that I have not yet completed the Safetycar package, which guarantees me a refund of the time value in contrast to the replacement value. For “only” 10 € /Mt. a) Does something like that work? b) Is the time value necessarily always essential higher than the replacement value? c) In a non-cash case, what replaces the opposing insurance? — Christoph
