In this paper we present a detailed spectroscopic analysis of the suspectedmarginal Am star HD\,71297. Our goal is to test the accuracy of two differentapproaches to determine the atmospheric parameters effective temperature,gravity, projected rotational velocity, and chemical abundances. The methodsused in this paper are: classical spectral synthesis and the {\it VersatileWavelength Analysis} ({\sl VWA}) software.  Since our star is bright and very close to the Sun, we were able to determineits effective temperature and gravity directly through photometric,interferometric, and parallax measurements. The values found were taken asreference to which we compare the values derived by spectroscopic methods. Ouranalysis leads us to conclude that the spectroscopic methods considered in thisstudy to derive fundamental parameters give consistent results, if we considerall the sources of experimental errors, that have been discussed in the text.In addition, our study shows that the spectroscopic results are quite asaccurate as those derived from direct measurements.  As for the specific object analyzed here, according to our analysis,HD\,71297 has chemical abundances not compatible with the previous spectralclassification. We found moderate underabundances of carbon, sodium, magnesium,and iron-peak elements, while oxygen, aluminum, silicon, sulfur, and heavyelements (Z $\geq$ 39) are solar in content. This chemical pattern has beenconfirmed by the calculations performed with both methods.
