Congrats on getting the VX "up to snuff", and yes, keep a close eye on your oil consumption. I check my oil, and usually have to add some, at EVERY gas fill up. Some people have had some luck reducing their oil consumption by cleaning the EGR valve and changing the PCV often (+/- every other oil change).

There are a couple of people here who have installed a cup holder in the spot that you are talking about. I THINK it's a Taurus cup holder, but I can't remember the year. Someone had a few that he was selling so hopefully someone will chime in.
