Yes, the 3 series includes 316, 318, 320, 323, 325 and 328. I'm not sure but I think also the 330 belongs to the 3 series. The last two digits tells what size the engine has; 316 = 1600 ccm, 318 = 1800 ccm, and so on. Many years ago I had a 316, and it had the same headlight arrangement as this car you've uploaded. It was the only model of the 3 series that had one single light on each side, the other models had double lights.
