To clarify we're talking best for you and not following some top ten cars of all time table. We all define best differently so if you were driving a souped up Thunderbird, Alcamino or, BMW ZHP then say whatever it was... and why.
So it's about best in your opinion/best for you. Someone might say it's their Hellcat... another might say it's their Chevy LS4 they transplanted into their Acura... anything goes.
