I've never had a hotel give me strange looks for arranging my own transportation, and this includes St. Regis and Ritz that may have had house cars waiting nearby.
There are many reasons a traveler would arrange their own car at all quality levels of hotel. For example, we use the same company for all of our Manhattan-to/from-airport travel. It would be frowned upon if I jumped in the hotel's car at 2x-3x the cost of what we already have negotiated.
