Today's #DavesCarIDService begins with an appreciative hat tip to Harry Bergeron for solving yesterday's mystery car
I'm gonna say a circa 1910 Cadillac touring, or a circa 1912 E-M-F touring. Accessory headlight gas tank on the running board.
E-M-F was for Everitt-Metzger-Flanders; Metzger was one of the founders of Cadillac, so there's a lot of resemblance between them. E-M-F was bought by Studebaker and name disappeared a few years later. Everitt went on to make cars under his own name.
1957 Chrysler or DeSoto, customized with '56 or '57 Packard taillights and simple bar bumper
1934 Oldsmobile sedan, and your grandma was quite fetching
mystery of the fender script is solved: it's a 1957 Pontiac Laurentian, the Canada-only equivalent of a US Pontiac Star Chief
Canadian content laws were such that US car companies had special model names for cars made/sold there: Acadian, Mercury Meteor, Pontiac Laurentian and Beaumont, Mercury and Fargo pickups, etc
L-R: 1951 Oldsmobile 88, 1938 Ford Tudor humpback, 1951 Oldsmobile 98, early '20s Ford Model T C-cab pickup, 1938-40 Ford Standard Tudor sedan
hmmm. split rear window= 1936 to 40 coupe, but gas filler cap high on driver's side rear quarter panel eliminates most of my usual suspects. Perhaps I can ask for some audience participation on this one.
if you're going to help nail this one down, potential clues:
1. unique gas cap location
2. taillight seems to be obscured by purse or bag on rear bumper
3. squarish (vs oval-ish) rear window shape
4. center trunk license plate mount

1961 Pontiac Catalina or Ventura bubbletop
1964 Pontiac GTO, the car that made John DeLorean the golden boy of Detroit before he was brought down in a haze of cocaine-fueled disco era time machine cars
1965-ish Lancia Flavia
hmmm, appears to be a fanciful custom, with aluminum body on an early to mid 1930s Packard chassis, maybe with a Packard straight 6. Hubcaps are def Packard. Can't really make out what grille badge says, but likely just decorative
Aha! Apparently built on a '32 Packard limousine chassis running a Rolls Royce aircraft V12.
1960 Lincoln Continental, last year before Lincoln went to the beloved slab-side, suicide door style used throughout the 60s. It's stock, it's real, and it's spectacular
yep, circa 1968 NSU Sport Prinz (another NSU Prinz is next to it). NSU was first company to use Wankel rotary engine; they didn't become Audi, but were bought by Audi.
The 4 rings in the Audi logo represent the merger of 4 car brands - Audi, DKW, Horcht, and Wanderer. First as Auto Union, then back to Audi.
Looks like Gramps was racing a '49-'54 Hudson coupe, just like Doc Hudson in the "Cars" movies. I salute him.
Grandpa's racing Hudson seems like a good photo to conclude #DavesCarIDService today. I will get to the backlog eventually, just remember to use the hashtag in your ID request.
