If it is, part of the reason you're getting silly questions is because you have a lot of words in your advert but don't actually say much.
Try and be specific about the work you've done and when it was done. Make sure you mention key things like service history and where it was carried out, when was the last one and what work was carried out etc.
Try and avoid statements like good for it's age, that doesn't really say much to a perspective buy.
Again if you've made upgrades, let people know how long ago the work was done and what the performance improvement was.
Looks like those aren't standard alloys either, provide some background as to why they are on the car and what condition they are in along with comments on the tyres (condition and brand).
Make some explicit statements about the bodywork, photo's on the internet don't show up detail very well at all, let people know if there are any dents, scraps or rust, if there isn't then say so.
What about the clutch, gearbox and electrics, no one knows your car you have to tell them, and it's a real pain to have to ring up or email to get basic info.
Don't forget to make mention of any service history, receipts etc. you have, how long you've owned the car, how many previous owners and why you're selling, it all helps, and people love receipts!
Just think of the kinds of questions and info you would want to know before trekking out to see a car and put that in your advert.
If this wasn't your advert, post a link to it and we can have a look and give you some more advice.
Best of Luck!
