These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Top Gear US
Accidental Innuendo: In the Big Rigs episode, Rutledge refers to Tanner's truck (a red Peterbilt truck) as a "nice Peter." Adam notes how wrong it sounds.
Broken Base: Despite confidence from the British trio themselves, fans on both sides of the pond have decried the US version. Reasons vary on the hate.
All of the features lost in US Season 3 (See below) pissed off a few UK fans and US fans who liked them.
Harsher in Hindsight: In the Alaska special, Adam's 1977 Ford F250 was described as "...[looking] like the Unabomber's truck". The special aired one week after the Tucson shooting.
Hilarious in Hindsight: During season 1, Adam would introduce the show by saying that they wouldn't be doing things done on specific reality shows. For episode six, he says that no one will be fired. In season 2, one episode had the three trying to find a car for a mystery celebrity who turned out to be Donald Trump. After deciding on which of the cars to buy, he directly told Tanner and Rutledge "I'm going to fire you."
The hosts' reactions to the forensic tests performed on their $500 cars. Let's just say the results were disgusting and leave it at that.
In the Continental Divide episode, they had to haul livestock in the back of their minivans. The livestock proceeded to stink up the vans and crap everywhere. In one van, they somehow even managed to eat the ash tray.
Suspiciously Similar Song: Due to US licensing laws, most of the music that plays in each segment are cover versions sounds similar but not identical to well-known music.
The segment on the Subaru Impreza WRX STI includes a snippet that sounds a lot like the intro to Metallica's "One."
They Changed It, Now It Sucks: Quite a few fans of the UK version that finally warmed up to the US version during the second season didn't take too kindly that much of the studio features carried over from the original (Stig laps, car reviews, Star in a Reasonably Priced Car) were dropped come season three.
Trans Atlantic Equivalent: Arguably (in some fans minds), one of the big reasons the US version's been as popular as it has is that it really does try to be as generally equivalent as it can. Including the attitude of "We are number one, every other show/car/country out there are number two or lower" that the original Top Gear had.
"I know, the rest of the world thinks Americans are arrogant. And, to be fair, fuck you."
