To be fair, unless it's on stupid miles, it probably only has had one service, or at least only have been due one service (although just clocked the miles, should have done at least 3).
Regardless, that service being missing means that the warranty will be void. Sure, you will get the ropey warranty from the garage, but that isn't what you want. You want the proper BMW Mondial warranty. And with 70k on it, that puts it in the expensive catagory.
As said above, it sound like standard M-Sport spec rather than "amazing" spec. It is also too high miles for good warranty. And doesn't sound overly cheap either. Almost standard 3 series aren't rare, so glad you got your deposit back.
