Looks like 2300 lbs but if you're comparing base trims that's 1200 lbs lighter than the base Mustang. A bit of a stretch for "about". And also a nonsensical comparison. Different purposes, different class of vehicle, different regulatory / safety requirements.
The Dacia Spring is available around here (Berlin), and while it's a bit more than that mass, it's close enough to be "about" a ton lighter.
