New presidential limo

Jalopnik is reporting that GM is working on a new limousine for the president, a version of the GMC Topkick disguised as a giant Cadillac DTS. Since the DTS is a bigger STS, which is a bigger CTS, You would think they'd call this the LTS (for limo) or maybe even PTS.

I've always wanted the limo fleet controlled by the Army so the president's car can be called Army 1 to match the names Air Force 1 and Marine 1, but that's just my natural neurosis for parallelism.
