I honestly think that them naming it "Top Gear" takes away from the shows credibility and really turns people away (especially the hardcore TopGear UK fans); they are trying to copy a long standing successful show even down to the name. If they would have named it something completely different, but kept the same format, I truly believe they would attract more people.
Despite what people say "oh it'll never be as good as the original", who cares!!! it's another automotive enthusiast show on TV, so heck yeah i'll watch it!!
Glad it is on the history channel, they have a really good line up now (I love Pawn Stars and American Pickers).
