Apologizes, I saw that I gave you the same suggestion twice!
Of course it's not wrong, it was just an advice and this is just a game and beside that, with the names it can be indeed quite difficult and your strategy is equally efficient (but risky  ).
He was E. L. James from Worcester, Massachusetts who built a 5 1\2 HP car around 1905.

13333: SCAD (2)

[targhediferro]

The Forest Automobile should be related with Forest Motor Co. Boston, Mass. 1905.
As you well know I was searching for something from Detroit more than from Boston, because I think this is the only way to reach Gerd!

Uhhh, this is tricky. Could it be the Savannah College of Art and Design which features automotive design courses?

He tried 29 numbers, you 10!
Your 2 games can be compared only after the same number of attempts.
Once someone reaches 1000 he is not automatically the winner. 
If he stops there with, let's say, 1000 points after 50 numbers, he will be the winner ONLY if, in the meantime, ALL the other active players (that will keep on playing) will not reach 1000 (or more) with less attempts! 

...and you can always hit a top maker out of luck! Remember that my index is not the bible and they are the top makers in my archive, not in the real world...just for example I use to list some makers by chassis, one by one and others just briefly...

(I know it's odd, but it's the only way to have a fair game...)

About your guess, it's not that Forest... 

[Wendax]

Fabrizio, if you want to reach the 1000 with less attempts than me, have a close look at the listing. There are some very hot numbers I can't try anymore.

It is tricky, but not for the reason you may think, I'm afraid...
Not Savannah.

I was wondering why nobody make that connection...it's quite sporty of you. 

[pguillem]

Let's join this crazy puzzle with a tribute to France : 1789 = ?

BENNET (2)

Nothing to do with France, I'm afraid, and nothing to do with the Gordon Bennett race.  Please let's try another number (and score a -10) : 1943 ?
