Spectroscopic investigations of seven
southern CepheidsWWCar, SX Car, UZ Car, UY Car, GX Car, HW Car and YZ Car have been performed. It was founded out six objects have metallicities, close to solar one and their CNO-, odd elements and Mg content
indicate that these objects are on the stage after the first dredge-up. CepheidWWCar is an unusual objects because it has noticeable overabundance of [C/H] = +0.3 dex, [N/H] = +0.95 dex, whereas sodium in deficient ([Na/H] = -0.46 dex), and magnesium content
is the largest ([Mg/H] = -0.12 dex) in comparison with other objects from this list having close pulsation periods.
