I have personally seen at least two different Pacer limos on the streets of Phoenix, Arizona. Real long ones. Recently, in fact, like within the last six months for the last sighting. There is a third Pacer that is stretched somewhat, about the same length as a full sized van, and it is lifted hugely with giant tires and four wheel drive.
We really need to see these, maybe a stakeout is in order?

The only Pacer limo I've ever heard about is the one built for Wayne's World II.
