We report the results of a detailed analysis of a deep simultaneous 130 ks XMM-Newton and NuSTAR observation of the nearby (z = 0.0315) and bright (L-bol similar to 3 x 10(45) erg s(-1)) starburst-active galactic nucleus (AGN) Seyfert 2 system: MCG-03-58-007. From the broad-band fitting we show that most of the obscuration needs to be modelled with a toroidal type reprocessor such as MYTORUS. None the less the signature of a powerful disc-wind is still apparent at higher energies and the observed rapid short-term X-ray spectral variability is more likely caused by a variable zone of highly ionized fast wind rather than by a neutral clumpy medium. We also detect X-ray emission from larger scale gas as seen from the presence of several soft narrow emission lines in the RGS, originating from a contribution of a weak star-forming activity together with a dominant photoionized component from the AGNs.
