Car appreciation... the aesthetics, the engineering, etc

It's not standard, but you hide that at the bottom. I would put a bullet point list right at the top with the headline stuff, because otherwise it just looks like a bloody expensive old car. You should be able to see why it's worth the money before you read any further.

Don't use language that makes you sound like a dealer. It's particularly too flowery in the Exterior section - it sounds a bit Swiss Tony. Just stick to the facts. Colour, the condition, list any faults.
Same to a lesser extent with the Interior section. Nobody cares that Porsche helped design the seats; just whether they are clean and untorn.

Finally, there are a couple of pics on the Flickr that look like during or before the paintwork. E.G. https://www.flickr.com/photos/8131181@N05/29956403956/in/album-72157685948864802/
Unless it really does look like that, I'd remove it as it makes the car look like it needs paint.
Should there be a bonnet liner? I see the originals are NLA, but I wonder if either a custom dynamat install or a quick spray with an aerosol over that primer would help?
