The 90s car era was the peak of the automotive industry in terms of quality, and the quality is a factor that first comes in mind when we compare two things. So the new mercedes has better features and better performances, better noise insulation, and more comfort, but the quality of the build is not better.

@philipgligorov5848 of course the start of anything will usually be it's peak and there's the highest demand, most competition and what not. But you can't say decades into the present that the older car is better. I'd take the newer Mercedes anytime of the week. I'd only take the older one out of style.
