Glasses guide please ?

Hi guys, thought would post here as its a mercedes.

Can someone with a glasses guide please give me a price on the below.
trade and retail.

2005 (05) A170 petrol auto Elegance, nice options (full leather, sunroof, parking sensors) not that options make any difference, tidy car with 56k miles.

I am potentially buying within the family so want to make it fair to all, I can price roughly via autotrader but would be nice to have exact numbers.

Many thanks.

Thank you.

I had in mind somewhere in the 4-5k range as being a fair price for a private sale.
