I kind of take offence to that.
It's actually a very hard way to write, because I had a joke in there about her car being a Pinto (which it is, I even gave it the license place from "Cujo"), but at the last minute we had to change it to something generic enough that we could bypass licensing issues. The problem with me being Australian is that our car models are different, so I went through a list of about ten or so other reasonable names I thought were free only to discover they'd all been used by American car manufacturers in the past.
The second thing is that the car, visually, is very clearly not this http://en.wikipedia.org/wiki/Mini_Hatch
, which is what I'm assuming you're talking about. It's not a huge problem at all, but you've just misread what she's saying. She's said "I drove a mini-hatch/mini hatch until..." the same way someone would say "I drove an Eldorado until...". The Eldorado is the type of car, Cadillac is the brand. It seems like you've read Mini Hatch as a MINI (brand) Hatch (type), which I can see how that would happen, but I haven't drawn the car to look like that -- that car she's driving is clearly and old piece of junk, which doesn't quite work with the notion of it being something from the Mini brand.
Also, as Erik is often quick to jokingly point out in many of our often public conversations, I was the one who jokingly set the date for the series. I personally don't believe ANY comic should hold to dates like that (for reasons pretty similar to what's been brought up here), but I did the math and in that first PCOC file put a very loose date in place for the hell of it. Erik may choose to completely discard that; I don't mind, I just put a blurred date on a paper for the sake of detail and balance in an image. Hell, I thought people would call me out on the way I draw Ecto and Venkman (which doesn't gel at all with the way Dan does) and as Laura Parr finishes, you'll see other things there that don't necessarily gel with what you've seen in the main series, but nobody's said anything about either of those things yet.
If something's a stumbling block, sure ask, that's what forums are for, and I'm more than happy to answer questions and clarify things, I'd just prefer you do that rather than call me a lazy writer when I shot emails back and forth constantly to ensure this story fit in as perfectly as possible. Initially it wasn't even going to be set DURING Haunted America, I'd wanted it to happen on the road home, but Erik preferred we set it between Roswell and Seattle and after talking about it for a bit and going over continuity issues in my own head I made it work. I have road maps of the entire trip drawn out (which you can even glimpse in #7's PCOC file), and heaps of other stuff, so, lazy; not so much. Last resort; kinda yeah -- because it kind of killed a Pinto joke both Tom and I wanted in there.
I'd also wait until the story's completely done with. Not everything is as it seems and nobody's figured it out yet.
