Relax dollface, #DavesCarIDService will solve your car mystery 
First up: the pre-Astrodome mustachioed Houston Colt .45 parking attendant is with a (L-R) 1956 Dodge Coronet, 1960 Cadillac Coupe de Ville, and 1961 Cadillac convertible
Another baseball-related request: the great Satchel Paige on the bumper of a 1940 Packard
This serious-looking gent is with a 1937 Plymouth coupe
Correction, a 1936 Plymouth as indicated by hood ornament. Plymouths of the time always had a Mayflower-themed ornament, here's 1936 vs 1937
This car, as well as the two in your follow up request, are all 1917-24 Ford Model T tourings
1931 or 32 Packard Town Car Landaulet, but almost certainly not with the original driveline. Plenty of room for a Costco toilet paper hoarding mission
This slice of the 1970s includes a 1968-73 Opel GT, the pint-sized homage to the Corvette from GM's German division
A 1948-54 Chevy Suburban under the Christmas tree
1946-48 Lincoln convertible (though not a Continental), with body radically customized by sectioning. Bumper is also customized.
*"sectioning" is a term for chopping a horizontal slice out of the entire body of car to give it a lower profile. One of the hardest customizing jobs there is. Here's a stock vs sectioned 1949 Ford
A 1949-51 Chevy Fleetline 2 door sedan lead sled featuring some other customizing tricks: chopped, dropped, shaved, lakes pipes & spider caps.
*all GM sedans at the time had a fastback body option (Chevy Fleetline, Buick Sedanette, etc) and they are notoriously hard to chop. Looks like a nice job on this Chevy, at least at that photo distance.
Once again, if you're requesting an ID please use the #DavesCarIDService hashtag and please be patient. I've got a 2-week backlog in my inbox, and if you just tweet a pic at me it will likely get lost in the shuffle.
Not 100% certain, but I think a 1927 Chevy sedan
This scene of neo-Noir from the East Village features a 1949-51 Dodge Coronet sedan
a circa 1935 Auburn 851 Boattail Speedster, and given the right hand drive and bucolic setting, I'm guessing this lost treasure is somewhere in South America
*several South American countries (notably Argentina) were left side of the road traffic before WW2, and transitioned to right side after. Prewar US cars in South America are typically right side steering wheel.
That's a 1940 DeSoto sedan behind them; perhaps a military uniform buff can help you pin down a year.
From this pic I can only say 1955-59 Chevy Suburban; need grille to ID specific year
This towhead youth is in front of a 1937 Plymouth with an aftermarket bumper dress up accessory & a raccoon tail on the hood
The forlorn remains of a 1949-50 Chevy Styleline sedan
The Refresho Fudgsicle man is in front of a 1953-56 Ford F100 pickup. Also, "Refresho & the Fudgsicles" would be a great band name
We have a Kaiser sighting! This one is a 1946-48. Founded by Henry J Kaiser after his success as a major shipbuilding contractor for the US Navy during WW2. He also founded Kaiser Aluminum and Kaiser Steel postwar.
His car building was a bit of a bust, but his compact model 1950-54 Kaiser Henry J was somewhat popular as a grocery getter. A rebadged version was sold through the Sears catalog as a Sears Allstate.
Another legacy of HJ Kaiser is Kaiser-Permanante, the first HMO

Now here's a fine looking couple snuggling on a 1933 Chevrolet
the third Packard of today's thread is a 1939, with a Von Dutch style flying eyeball pinstriped on the prow
Apparently I'm running a fire sale on Packard IDs today. This fourth one is a sporty and stately 1935-36 Packard Twelve coupe
This one was a real struggle to ID, but I'm pretty sure a 1928ish Hupmobile Century. Pic is probably a few years later than you thought.
What you got there is a circa 1950 Crosley Hotshot. Crosley was a company in Cincinnati that made radios, and decided to go into the microcar biz briefly. Hotshot was the sports car model. Crosley has been resurrected recently as a retro audio brand.
Packard #5 of the day is this 1955 Clipper Constellation
1949 Buick Roadmaster ambulance, and the pic gives me nostalgia for all those fun trips I had in one to the Iowa State Nut Hutch
1935 Ford stakebed, and a handsome truck indeed
A 1929 Cadillac (as is implied by the vanity license plate). This on a V8 Fleetwood Town Cabriolet.
1954 Plymouth Belvedere
One other ask for those sending me ID requests- please keep it to one per week so I can get to other folks' requests.
Not a lot to go on here, but I sense a 1980 or so Chevy or GMC conversion van
best as I can tell, a 1942 (or 46-48) Ford Super Deluxe
Here is that photo of Grandma & Grandpa Leone, and a fine one it is
Must have been a hell of a party. Through the beer goggle fog I think I can make out a 1941-46 Chevy or GMC pickup
I believe these suds are being hauled by a Waverly Electric. There were plenty of electric car and truck makers more than 100 years ago; Baker, Detroit, Atlantic, Waverly, and more.
They arrived in style in a 1924-25 Ford Model T "phone booth T" coupe.
The unmistakable roofline and rear pillars of a 1961 Ford Galaxie 500 Starliner 2 door hardtop
Man, that's a fun photo. 1928-29 Ford Model A Tudor.
and a less fun photo: best I can tell is a 36-38 Chevy or other GM humpback sedan, with I think a very early Tucker Sno-Cat coming to the rescue, before they avalanche down that precarious dropoff
Had to do a double take on this, as it is a Ford Model T, but pre-1917 (when the US entered the war) and right hand drive. But turns out Ford supplied WW1 vehicles for the British before US officially entered. Note "RAF" on door
