Hi Toby.
Your advert is well laid out without being too long winded.
The only thing you could improve on is the pics.
Whenever I sell buggies I always take pics in the daylight, I'm not sure if you have, they seem a little dark. I'd also take a few more with close ups of the rear end of the car showing the drive cups and pins so potential buyers can check for wear. A couple of close up shots upfront and centre would help.
