You don't need to have an "originality" neurosis to have a problem with this.
Some years ago I visited the museum of the Berlin Philharmonic--a great collection of musical instruments of all periods. They had a harpsichord that was owned by JS Bach, and it was in the process of being restored. Now, <span style="font-style: italic">that's</span> an example of an item with great cultural and historical significance. Anyone restoring that instrument better be one of the top experts, and even he will have some dilemmas to face. On one hand, you want it as original as possible, but you also want it playable, so people today can have a sense of what Bach heard.
Triumphs, as much as we like them, don't have that kind of significance. So, at first appearances, it's a little hard to fault someone for doing an, uh, <span style="font-style: italic">individualistic</span> restoration. Worst case, the world is out one TR4. Not an earth-shaking tragedy.
At the same time, there still is something called <span style="font-style: italic">taste</span>, and I think this car shows little of it. I see a lot of dignity in these cars, and this one has lost any it once had. It's been turned into a joke, and not a very funny one. Not a tragedy, perhaps, but still nothing to smile at.
I suppose I could grant the restorer some credit for trying to do something special, even if it didn't work. But that's as far as I can go.
Finally, I know that the owner may be reading this, and I regret any offense; none is intended. However, there is an issue here that is worth exploring: how far can one legitimately go in modifying one of these cars, and what are the implications? I don't want to see such discussions censored simply because someone might not want to read them.
