I think he means zero, Eg 1.01, 1.02, 1.03 etc.
Also now that this is done, it should be moved to archives.

What's a cero?

You must put a cero between the dot and the number of the episode Kooshmeister.

Done,

Red car is a Mercedes

That's the joke. Although Batmanuel treats it like it's the best car ever. For instance he double parks at the mall, because, "I will not subject her gilded doors to the threat of dings."

And, "The Terror" had no cars in it, so no worries.

The "Batmanuelmobile" is nothing more than a 1960 Buick. The van at the pet store is a GM, but I can't tell if it's a Chevy or a GMC. The car above the pet store van is a Chrysler, possibly an LHS.

From episode six, "The Funeral:"

Lincoln Towncar limo. 3 stars.

Police car. 2 stars.

Mercedes. 1 star.

From episode seven, "The Tick vs. Justice:"

Destroyo's Mercedes. 2 stars.

Jeep Grand Cherokee. 1 star.

Ford Explorer. 1 star.

From episode eight, "The Big Leagues:"

Car seen on security footage of Batmanuel (ineptly) foiling a robbery. 1 star.

And that does it, the show only lasted eight episodes. There is a ninth, unaired episode, "The Terror," and it's on the DVD but I'm uncertain how to handle it, or even if any cars appear in it (I haven't been through it yet). If any cars are found in it would they automatically be considered "deleted scene" material?

Yes, the incredibly silly live-action version of the incredibly silly cartoon. Here are the cars from the first episode, the aptly-titled "Pilot."

Bus. 2 stars.

Checker Marathon (?) taxi. 2 stars.

Van. 2 stars.

Car in the middle. 1 star.

Tow truck. 1 star.

From episode two, "Arthur, Interrupted:"

Captain Liberty's motorcycle. 2 stars.

From episode four, "Arthur Needs Space:"

First appearance of the "Batmanuelmobile," which goes on to appear in two more episodes. 4 stars.

Truck. Chevrolet? 2 stars.

Take your pick. 1 star.

White car to the Tick's right (our left). 1 star.

Red car of some sort. 1 star.

From episode five, "Couples:"

Foremost car in front of the diner. 1 star.

Car to the right (policeman's left). 1 star.

Pet store van. 1 star.
