I had a Fiat 850 sedan in the seventies.
I upgraded it with a 903 cc Spider engine, front disc brakes and real mag wheels.
I had a lot of fun in that car.
This car is even smaller and cute"r. I couldn't help myself.
600 cc monster. Suicide doors.
Can you say "sei cento" ?

Cool.

Neat little car.

Why did I immediately think hybusa

very cool

Looks like Fun. Guy in my neighborhood has one and a 60's Multipla.

The Best of France and Italy Car Show is this weekend here in the LA area (SFV) Lots of old Fiats. Last year one guy had one with a honda Motorcycle engine and trans!
There is also a small swap meet! What do you need?!? HA!

If you want to turn its personality into an ass kicker: https://www.zcars.org.uk/home/news/fiat-500/

600cc. How many cylinders?

It's Italian, twelve cylinders.
Actually 4 cyl. , water cooled.
500s were 2 cyl. air cooled

That looks like my hamster fan

I'm thinking a 110c.i. Screaming Eagle V-Twin... got the torque, got the sound to turn heads!

Very cool. If you're not restrained by keeping it OEM, "bike motor" seems a cool answer. Heck, the OEM motor might be worth a few bucks to someone interested in a more factory restoration. Interesting what you might do with a 600cc bike engine, just to keep with the 600 theme. Although in this case, I think bigger really would be better. Maybe with a turbo...

Love it.

It's a 1959.
1959 was the last year Chrysler offered the 392 Hemi.
Fiat and Chrysler are now partners.
It's getting a HEMI !

If thats your logic, they also have Ferrari and Maserati, or yes Lada

I've seen a couple with VW type 1 engines.
One used to be at the north east VW drags all the time in the 90's.

......not really.
It is absolutely un-molested with all original paint......it'll remain that way.
It'll get some rust repair and everything will work as it should.

Does it have Flintstone floors? Mine had.
I'm sure you'll enjoy it!

Neat car. Is it a teeny 4 cylinder in there?

Partial Flintstones.
No vaccine then, European epidemic.

How many clowns fit in that thing???

Ask Todd

Just don't get hit by someone on a bicycle... I think you'd lose...
