Make sure you have a reserve set on it.

Take Very clear and detailed shots of the car, when it is cleaner than the bible and polished to the nines - a dirty car wont get anyone excited.

Keep the description short, clear and factual so give the reader/buyer all the info but without pages of waffle.

Make sure you get cash on collection of the car - use paypal for a deposit at most. DO NOT RELEASE THE CAR UNTIL CHEQUES ARE CLEAR if banker draft or cheque and ask to see id - most peole have a driver licence on them, make a note of the address and see if the seller asks for the same address on the log book when you fill it in - if not, why not?

If cash, check it is real, and make sure you have a friend or two in the house when a buyer turns up.

ALSO Do not give out you full address to anyone, give them a postcode to get them to the area and then ask them to call you when close by. This prevents people getting your address, not showing, then to turn up and nick it a few days later.

I would personally try pistonheads first as it is free, or pay 20 quid and stick it on here.
