GuessThatCar contest - Last Day! End of the competition!

And this is it! The end! Unfortunately, there's no brand name starting with an X so this will be our last day, guys.

I would like to thank each and every one of you for participating, it means a lot. I hope my next contest will be better than this, too. :)

But now, let's get down to business, one last time. Our last time winner was @j85063, again - congrats!

The letter of the day is

Z.

Don't laugh, please. :D

Hint 1: Manufactured in a country that doesn't exist anymore.

Hint 2: At one time it was exported to USA.

Can you guess what it is?
