i WANT TO SELL MY 1997 HONDA CRV IN MINT CONDITION WITH 23000 MILES

Hello stefan5536-ga,

Your 1997 Honda CR-V has below average miles for it’s year and
described as mint condition so should fetch the best prices.
To get a rough valuation of your car you can visit What Car?
magazine’s online valuation tool:

or the online Parkers guide which is used up and down the country to
help people price effectively:

As secret901-ga pointed out ebay is a online venue for selling cars,
Here is the UK motor auction site:
http://pages.ebay.co.uk/ebaymotors/ 
Though car selling online by auction is a relatively new concept in
the UK, instead of being bargained down on price, your buyers are
upwardly revising the price instead! UK’s ebay is in association with
the well established Exchange and Mart.
If selling by auction doesn’t appeal, here is Exchange and Mart’s own
site:
http://www.exchangeandmart.co.uk/

Preloved.com looks to be another with wide coverage.

Perhaps eBay would be an appropriate place to sell it.
