My guess having had similar in the past that the call was not from Enterprise, though they do higher cars to MB, but from the other party insurers.
You just can’t believe how fast word gets about, not from yourselves, but from the other party looking to reduce their claim. Last one I had was about 4 years ago under RSA insurance as was then. Someone drove into the back of my 2 month old MB car and made a hole in the plastic bumper plus damaged a parking sensor. This was about 500 yards from my home and by the time I got home, 5 minutes later, my phone was ringing from the other parties insurer, I kid you not. They wanted to do a deal to repair the car along with a bit of cash in the hand and when I told them it’s a MB car so out of my hands they just hung up.
Then I had the many, many, many calls for a year after from the “about your accident brigade” and about the £1,750 cash waiting for me just for making a claim.
My car is adapted so not any old hire car will do but MB suggested I used taxi’s at their expense so asked “do taxi have hoist in them these days”. Anyway in the end I told them I was quite happy to drive around with a hole in my bumper for the next 3 years until the lease finished and low and behold they found a hire car with a hoist in and the other adaption I needed before the week was out.
BTW Enterprise called me twice within an hour of each call that day, same caller asking the same questions and when I asked him why he’s asking the same thing over he said for security with that I just put the phone down on him.
They tell me that DL are worst than RSA so I hope for your sake it isn’t and best of luck.
