Additional cars of note:

WP45 G1A 105427 - Dodge Coronet Station Wagon, assigned to track use

JH27 H1B 358847 - AKA the "Judy Ham" car
This is a "clone" car and not an actual pace car.  According to Gene, the VIN number of this car puts the build date too late in the year for it to have been at the Indy 500.

One of the first owners of this car was Judy Ham of Lexington, KY.  (One source tells me that she was the original owner, others say she purchased the car used.)  She is credited with adding the pace car lettering to the car.  A friend of Judy's tells me that she purchased a set of cling decals at a swap meet but then decided to preserve the original decals and instead had the lettering painted on the car.  "She just wanted a clone car and was not trying to deceive anyone," says Ron Snowden.  Ron says that when Judy sold the car many years later, she was very clear that it was a reproduction, not an actual pace car.  Unfortunately she also sold the original decal set with the car, which may have added to the confusion and given credibility to claims that it was an actual pace car.  This car also has a rally hood with a hood scoop, which none of the track cars had.

As of October 2002, this car was owned by Gary Fazenbaker.

JH27 G1B 293393 - I received an email claiming that this car was one of two Y28 public relations cars provided by Ray Johnson of Shadeland Dodge.  The owner at the time (Jim Hostetler) referred to it as "#3 of 52 pace cars built" and says this has been verified by Galen Govier.  As of February 2004, this car was owned by Todd Martin.
