All those rebuilds don’t work out financially - it’s YouTubers gaining revenue from the videos and advertising that make them financially viable.
Look at Matt Armstrong’s latest with the ex-Marcus Rashford Mansory Rolls Royce Wraith. Radhford shelled out £700k on it. Matt has repaired it using another doner Wraith and spent £300k+. Would anyone in their right mind with £300+k for a car buy one that had been smashed up and had second hand parts put on it from a higher mileage car? I’m not sure there is a market for such cars.
In contrast, when he does a more mainstream performance car I think he doesn’t have a problem raffling them off and getting enough money back.
So this SVR build is unlikely to come out financially viable, as the car will always have a crash category marker against it, which will narrow the likely buyers, it has a second hand replacement engine, which again is going to put many buyers off, and unless it is an absolute bargain, why would anyone buy it over a genuine car with full service history and no crash/ flood history? I see he’s selling raffle tickets for it - that will be why…
