When UK engineering meets United Kingdom craftsmanship, the result is one of the most compelling matchups in the classic car world. The 1921 Bentley 3 Litre and 1934 Riley MPH Standard embody their respective national automotive traditions while competing in the same arena. On paper, the two are remarkably close in power output, with the 1921 Bentley 3 Litre producing 80 hp and the 1934 Riley MPH Standard delivering 70 hp.
