Gulfstream!
Some history
The gulfstream 1 was an attempt by grumman to make a private plane, yeah thats about it. Its quite a small but fashionable aircraft, and over 209 were made, flown by people such as walt Disney!
The gulfstream name and branding is quite well-known, but this is the only one on this website as far as I know.

This one is surprisingly close to the original, it has slightly lesser fuel, and its max speed is somewhere around 400kmph, enjoy!

This was a submission to the 1960s challenge, since its production run was well into the 60z, despite being first made in 1959
close enough
