Interestingly, my Ludicrous upgrade receipt clearly states that I received a "P90D Ludicrous upgrade." I have been curious since if that's a data entry error, an oversight, or if they only made 1 kind of upgrade (which would make the most sense). ow I have to also be curious if it matters in my ability to upgrade to a P100D.
Not that I'm sure I'm ready to spend another $20K on this car.
