be aware with gumtree , I listed a car for my daughter on gumtree last year , gave my phone number as she wasn't confident dealing with enquiries, within 5 mins of listing the calls from ambulance chasers started, , "hello we are calling about a recent accident you had in (insert the car I listed). I had 4 calls in the first 15 mins and removed the phone number from the ad , and said email enquiries only, the calls continued for a few days after, shysters they are.
the car did sell via gumtree and for the asking price
