its not a duesenberg.

some more clues ,

The X was introduced around the same time Cadillac introduced their V-16 powered automobile. In comparison, the X built automobile was more powerful and an engineering marvel. By using aluminum, the 491 cubic-inch engine with its overhead values weighed just over 900 pounds. The engine was formed by merging twin-eight cylinder engines in a 45-degree angle, giving the engine an impressive look and an astonishing 200 horsepower. The use of steel cylinder sleeves added to the longevity and durability of the engine. The V-16 engine earned Mr. X the Society of Automotive Engineers annual design award.

The engine was an engineering marvel and the automobile was a work of art. The problem was the timing; introduced near the onset of the stock market crash and the crippling Great Depression. The most competitive market segment at this time was the upper, high priced vehicles. Packard, Auburn, Cadillac, to name a few, were produced exquisite automobiles and catering to the wealthy. The short list of buyers meant production was low and the profit margin was tight. To stay competitive the manufacturers needed to continue to introduce new products, designs, and innovative vehicles.

I know the answer... It's in the title of the JPG file when you save the picture to the hard disk: Marmon V16.

It's a bit of a cheat, so I think Taxexile can post the next one.

an honest man there , here is another american car , this one is easier to recognise , but no less impressive.

1959 Buick. Can't see, but either an Electra or Invicta.

yes , im also not sure of the model.

stunning car though , imho those were the last years of outstanding american car design . those designs are just jaw droppingly fantastic.

over to you p.b.

I don't have access to photos like my Renault Alpine convertible, and that last one was too easy. taxexile, can you do another round please, maybe something more like an Fairthorpe Elektra or a Berkeley? Wait, I'll PM you with some crazy ideas.

this should sort the men out from the boys.

Sorry, taxexile, that one doesn't seem to work. Was it an Armstrong Siddeley Saphire, or a Humber Hawk?

ive changed it from a .bmp file to a .jpg file , its showing now.

its not british.

Looks like an old Studebaker Champion.

It's not an Edsel or a Tucker. I'm going to make wild guess and say it's the General Motors Y job, or a GM dream car like those shown at the Motorama shows from 1953 on. Cadillac Espada, etc.

although it looks like the y-job , its not american believe it or not.

I thought you said it wasn't British. Let's see, it appears to have a right hand steering wheel. Not Canadian. Mid or late 1950;s with that wrap around windshield, and more likely mid 1950's since there are no fins. Oh, maybe a Tatra? I'm joking as I never heard of a Tatra convertible....a Pegaso with body by Sautchik?

with tatra you are heading in the right direction geographically.

Tatra was Czech; there were no Polish or Romanian cars I can think of...surely not a Brabant! C'mon, don't tell me it's a Russian model like a Zif. No, those are left hand drive....I know it's not a Monteverdi or a Fiat Topolino...it is so mid 1950's, so large...

don't tell me it's a Russian model like a Zif. No, those are left hand drive

do you mean zil ? ........ its a russian zil ! they originally used buick engines.

Good grief, and I was over there in May and June, being driven around by taxi drivers who were on the left side. Was the zil their big car, like for parades?

If it's my turn, I still defer to the taxexile. I sent you some ideas that should be difficult to recognize.

this one is courtesy of peaceblondie , i've never seen this before and had no idea what it was.

It is American made, and I think it won the index of performance, either at the LeMans 24 hour race, or the Sebring (Florida) 12 hour race. Later, French Alpines won the LeMans index of performance, which favored small displacement engines.

it starred in a childrens programme if i can recall

Correct, but was it because I left that link at the bottom of the pic?

correct but what about the power unit???

I can't play this game. I don't like cars, don't pay them much attention. Hired a car in the UK, drove it back to where I live stopping to go in a shop on the way. Came back out and tried to get back in the car. No joy, key didn't work. Then a lady came out of a hairdressers, arms waving madly yelling something about her car. Ok, lets give the car behind a try. Yep, key works fine on this one. Thought I'd better have a propper look at the car, a new green Nissan. Only had a few miles on the clock as well. Her car was a 5 year old grey Sierra. She had a very confused look when I drove off.

Anyway, here's another car for you. One careful owner

Daimler?

I had an Ami 8 estate! - 604 cc of raw power - cum-on feel the ergs!

Talking of which......

a trio of tatras

A trio of Saab

Just read this threat....

Will try to find some special ones in my books

OK this one should be easy

Trio of Tatras - you can see how Porche stole the idea for VW from these pre-war vehicles

and this?
