I've been following this thread with some interest as I have gone the rally car route on my BN4. It has been argued that originality is what most buyers want, but the author of
https://www.mossmotoring.com/a-bright-road-ahead/ points out that modifying LBCs has been part of the hobby since they were new and appeals to the potenital younger owners. That's a matter of the owner's taste, and that means by definition that not everyone agrees. My feeling is that if your car wins it's class at shows where judging is by popularity, then most people would agree with your modifications. Mine usually does well, but at a British car show last year my class was won by a early 3000 with a nicely-done Ford V8. So being heavily modified doesn't necessarily mean no one will buy the car. I do think, that barring a historically-significant car, a concours winning original car will bring more money as most people recognize the extreme effort that goes into a gold standard car.
I agree with much of what has been said here:
- The description is too long.
- The history of where the car's been in its life is distracting and unimportant. Racing history should be left out unless it's historically important, e.g. "won 3 of 5 races at Watkins Glen while driven by famous driver ___", "won SCCA championship 3 years in a row", etc.
- Drop the term "bling".
- Likening the hood louvers to those on a 100M makes it sound like you are claiming something it's not. Louvers are fine, just not the description.
- I think the same goes with the 727 URX registration sticker. Even though my BN4 sort-of pays homage to UOC 741, I wouldn't put that registration sticker on it.
- I think the white coves don't go with the flairs and rally vents. They should be more subtle.
- Remove the back supports from the seats and take a new interior photo. Makes me think the seats are uncomfortable.
- Have a photo of the dash.
FWIW, those are my thoughts.
