10. Infiniti M45
The Infiniti M45 delivered an enticing mix of a robust V8 engine and a balanced, agile chassis. It could easily hold its own against rivals like the BMW 5 Series and Lexus GS, offering luxury and performance in equal measure. Yet, Infiniti’s underdog status in the luxury segment meant the M45 rarely received the recognition it deserved. Despite its strong credentials, many buyers simply looked past it, missing out on a true competitor in the executive sedan world. [Source]
