I think the choice of a CSS over a TCR was a sensible one. One of them is likely to depreciate a lot less (if at all), be a lot more fun and generate much more youtube interest.
Buying cars for YouTube interest is a tricky one, in the six years I've been making videos, lots of channels have had lots of views and earned a lot of money by doing videos on Mk7 Golf R and now Mk8. It would be disingenuous of me to start championing this car because simply I prefer a GTI and this sincerity has definitely cost me views and slowed down the growth of my channel.
Now YouTube is my only source of income (simply revenue from the ads I have no control over, not sponsorship etc - rarely more than 3 figures per month) I've had to consider whether sincerity pays the bills, it's certainly not high on the priority for a lot of people in this business.
The Clubsport S came about because I was thinking what to do with my Leon Cupra 280. Modifying it would mean a commitment to keeping it and recent surprisingly popular reviews on my wife's TT had made me realise it wasn't actually that popular on the channel. So man maths at its finest meant I could justify a CSS and stay true to my widely expressed GTI preference. Rather than repeat videos from six years ago when I still had my first one, this car will get used properly as life is too short and nobody really uses them so it should be decent content but still unlikely to get anything like the numbers of a much cheaper R as it's still very much a niche car, which is fine as I've never really aspired to be mainstream, just need some decent solid viewing numbers and no more.
Around the boom time of car reviews, and cars that were interesting to me, the MK7/7.5 GTI and R, S3/RS3 and M1351 and latterly the 128Ti (which now drive) used to watch all the known names pretty regularly but there is a tipping point where you lose interest a bit and switch off from some personalities, and admit to now only watching all your content, Mat from Carwow, Thomas at Autogefuel, and bit of Joe Achilles as assessed the worthiness of selecting a 128Ti and everyone else has pretty much faded away.
Think your biggest USP is that your history and experience support the thinking that everything do is a genuine and honest review, and that everything you do, is likely a question we would all ask ourselves on a certain car or element of the car. Basically you are seen as one of us, where many out there are talking at us.
Your reviews on the TCR is what swayed me away from just getting another R at the time, and selecting that TCR proved to be a very good decision, truly loved it, and was sad to see it go.
After this 128Ti, my run of some pretty decent company cars will come to an end, and will not be buying new and its likely that will go back to a MK 7 something and though could never get a car without rear seats, the standard MK 7 Clubsport does appeal, so will be going back over old reviews such as your TCR vs CS and seeing if heart will dictate next ride in about 12-18 months.
But just keep following doing what enjoy doing
