I think your add is well written and presented.
I would be temped to say who has done the cambelt and water pump, you likely also had the aux belt changed so worth mentioning that too. Tyres look like Michelins (are the new pair also?) If yes make a point of it.
Car presentation/comments (written as I think of them):
You photograph some curbing but I don't think you mention it, in fact you don't mention any bad points (all car have something to mention). I would be tempted to fit some different center caps as the silver speedline ones stand out like a sore thumb.
Again, large dents in the bonnet but not mentioned in the add, I would get a dent man out to sort as it will make the outside look a ton better.
You do mention something about the radio not working, is it much work to reconnect the speakers or to buy a cheap amp to get them working again?
You make no mention of rust, these are getting to the age now where rust is becoming an issue, filler cap, sills, are behind rear door cards etc. If it has some you should maybe quantify how bad it is, if it has none you should make a point of it.
Gearbox, often at those miles they crunch when doing a hurried 2nd to 3rd shift, if yours does not you should point that out too.
I personally would not mention track days, it doesn't look like a track car.
You do not mention servicing, oil changes, brand of oil used and frequency.
The exhaust looks very wonky - again not mentioned. Likely failed mounts. I would personally fix that and then take a simple but clear picture from every side of the car. Include an under bonnet shot.
You list parts (things which have been done in the last 12 months) but do not say who they were done by or what brands the parts were.
I do not think you have priced the car badly tbh, with a few more details and some better pictures I think you will sell it. Where else have you advertised it?
My take away from looking at your ad is that it is a nice car but likely has more going on than I would like to get involved with, ie, filler cap rust or other... The reason that it my thinking is due to the lack of 'bad points', like you are avoiding mentioning bad points because you think people will be put off.
Good luck with the sale.
