Not really. We're quite familiar with Chris Evans in the UK, as he's been a huge part of the culture for a couple of decades now - from BBC Radio 1 to the Big Breakfast, to Virgin Radio and TFI Friday, to BBC Radio 2 today, he's been on the screens and airwaves for 25 years.
His performance on the first Top Gear has very little to do with it. Evans 'became' a car enthusiast when he sold Ginger Media for a quarter of a billion pounds and acquired a new and much younger wife (he bought her a Ferrari after their first date; she was 18 and had no driving licence).
He's also been in the papers too. His car reviews in the Mail on Sunday are amongst the worst things committed to print (including Fifty Shades of Grey and The Da Vinci Code)... More on this lower down.... about expensive things, famous people and publicity - which is a common thread of his on-screen and on-air character (and, if reports of his marriage to Billie Pipe are accurate, off-screen and off-air character too) across those 25+ years.
I mean, fair enough. He made tens of millions of quid being a jovial 'anti-establishment' celebrity shill and spent it on James Coburn's Ferrari 250GT California, James Hunt's Hesketh, an example of the most expensive car ever sold at auction - and so on (notice how they're all 'the first' something or 'the most' something), and then painting just about all of them white because he likes it and shoving them into a large display case in his garden. Good on him. It doesn't make him a car enthusiast.
Nor does it disqualify him, admittedly. It may be that he's always been a car enthusiast and the Ferraris he's bought have been the cars he really wants after years of passion for the brand were finally brought within reach due to his success. He's also owned a Morris Minor, a VW Beetle, Chitty Chitty Bang Bang and an Abarth 500 (Ferrari edition, of course).
Personally, I think his Ferrari collection (and Carfest) doesn't have anything to do with whether he's a car enthusiast or not. It's his writing about cars that really speaks to it - you just have to read a Chris Evans review to show how little he cares about cars outside of his very narrow interest envelope. Unless it's expensive or fast, it barely counts as a car review, commonly featuring eight columns of an anecdote about someone famous and then one column about the car. In fact the one I read last week was an expensive car - the Rolls Royce Wraith - and the car didn't even get a mention until the second page. He gave it five stars.
For me, Evans is no better than Hammond on this front (though he is on many others - he can act, for a start). Evans is not a man who will spend an hour to pore over a Mazda 2 or a Skoda Yeti - though he might write nice things about them (even if it always gives an impression that he's been incentivised to do so)*. His track record is that for him to be interested in a car, it has to be old and quirky or, old or new, expensive - and to me that's too narrow a scope for the generalised umbrella of car enthusiasm.
Which also disqualifies a lot of people who only like American cars, or only like old cars, or only like BMWs - and so on.
*And I'm not saying you have to write nice things about or even like more mainstream cars in order to qualify as a car enthusiast. I just think that Evans's attitude towards cars is more... Sultan of Brunei than Rowan Atkinson
