I always kind of saw Lightning as a tall, blonde type guy. Sally is kind of tough but she kind of makes me think of a short, burnette type girl.
I imagined them looking something like that^^ myself.
[size=85]I think Lightning and Sally would both be blondes 
[/size]
As for Guido, I think he would have either black or brown short wavy hair. Blue eyes, very short and thin. Maybe a small mustache, or no facial hair at all. He would always wear a beret looking cap too. 
I could definitely see that for Guido.
As for Mater, he always reminded me of the actor who plays him.
That’s how I see him.
I think that’s pretty acurate to how I imagine it.
[size=85]MissCarrera, that sounds good to me 
Mater is Larry The Cable Guy 
, like I said, he has a soul-Mater instead of a soul animal 
[/size]
That’s how I picture him too, except with big brown eyes. 
That’s curious.
The eyes should be the only part nobody would have to imagine, since they already have them
And yes, the original Guido eyes are brown.
[size=85]^-^ I think big brown eyes, because, yes they are the original color.

I can’t really picture Lighting McQueen looking like Owen Wilson too^^.
Oh, haha, I was just going from memory on the Guido description. Brown eyes it is. Either way works for me.
Oooh! I like that visual of McQueen too!
I love that human McQueen as well, I wanna say I shared some of the artist’s other human Cars characters before. They’re uber talented
I was surprised to see that there was a topic on this, because by the time Cars 2 started rolling around last year and I started getting obsessed over it, I starting drawing the characters as humans, due to my lack of ability to draw vehicles at the time. I drew a LOT of them on DisneyCreate, my favorite online art community (www.disney.com/create). Look for my stuff! You’ll know it’s me when you see a Cars-themed screenname and my portfolio is full of Pixar art… including a number of humanized Cars characters. I’ll post some of my art here when I have the time to draw something really worthwhile. I do have a picture of Lightning, Mater, and Sally in Christmas outfits that’s pretty good… but because it’s May, I don’t know about putting it up now. Anyway, I totally see the whole thing with Lightning looking like Owen Wilson! I think my most unusual design is Mater, who started out looking more like Larry The Cable Guy, but well, after Cars 2 came out, I started making him look younger, and well, let’s just say my brother said he thought the end result looked a lot like Leonardo DiCaprio! But hey, there must be some reason a lot of girls have had a thing for him before Holley came in! 
Interesting! I tried looking for you but there was too many. 
Could you maybe post some here? It doesn’t matter about the Christmas thing! I’d love to see it. I have a drawing I drew of Lightning and Sally at Christmastime on art page if you want to see it.
Heh heh… sorry about that, I should’ve probably mentioned my screenname. I go by CARSGirl, though I haven’t drawn much on Create in a while, so you’d have to search for me, and the search engine hasn’t been updated in some time so all the drawings of mine that come up are really old. But then you could see my page. Thanks for taking an interest! I saw your Cars art and I think it’s so cute! I love the way you do them! Oh, and I will post some more of my stuff soon!
I just looked through your gallery. I loved them! Especially your Finn McMissile one and the “tire-five” moment between Lightning and Mater is so good. I got to give you props for drawing cars. I can’t do that to save my life. XD Thank you! I look forward to see more from you.
Thanks so much again! Drawing vehicles is no easy task… I can really only draw them if I have a reference in front of me and have a lot of time on my hands Once again, it means a lot having your support! I look forward to seeing more art from you, too! I’ll send you a PM when I get the chance!
so here’s my basic, how i picture everyone in town:
McQueen: taller, dirty-blonde hair, slender, slightly muscled, and usually (not on race day) red converse, jeans, and a Rust-eze, Rt 66, Radiator springs, or other random (always red) t-shirt
Sally: tall, light brown wavy or curly hair (with natural blonde & red in it), thin, but not that scary-unnatural thin (like, she has a little muscle, a natural amount), usually (not on court days, though i don’t see her getting too dressed up for court, everyone knows her except the criminal) light blue converse, jeans, Rt. 66 (or other Radiator Springs related) t-shirt (usually light blue)
Flo: about like everyone else has said, waitress outfit in her paint color, graying hair
Ramone: Tall, little mustache (like the thing above his mouth in his car-self… its not really a grill… idk what it is) paint-stained jeans and shoes
Red: i agree with whoever said “Gentle Giant” earlier, but, of course, he always has a watering can or hose with him for watering the flowers
Mater: a very Larry the cable guy- like guy
Lizzy: elderly, white hair, false teeth, asleep in a rocking chair on the porch
Luigi & Guido: both shorter (though Luigi would be a little taller than Guido), both would have a little hat, Luigi’s would be black, Guido’s Blue, Guido waring overalls over a dark blue t-shirt, both stained with grease (from the greasy bolts on tires, and dirt on old tires) and his little drill in that loop in the overalls, a rag (to clean the hubcaps and bolts) hanging from his pocket. Luigi would also have overalls, but not satined with grease, just dirt on the knees and a t-shirt under his overalls too, and Luigi would also have a mustache similar to Ramone’s (the emblem in Luigi’s case)
~random question: does anyone else think Guido’s eyes look PURPLE when he’s dressed in his Ferrari gear during the dirt race in Cars 1?
Filmore: Hippie… complete with tye-dye headband (though graying hair), tye-dye t-shirt with that vest Ken has in Toy Story 3, a peace necklace, bell-bottoms, glasses, little beard (like his licensee plate) you get the idea
Doc: i want to picture him in kakis, with a blue shirt (but that could be because everyone in my family from that time period wares kakis when they aren’t working in the garden, something about getting blue jeans at the hardware for $0.50) with greying hair and glasses, plus a mustache (like his car-slef has)
Frank: the evil rancher down the road kinda like in Second Hand Lions, sitting on the porch with a gun ready for the trouble makers ~coughMaterCough~ to disturb his cattle
Hahaha! Yeah. Although Frank is supposed to be a bull.
