Best place to advertise a car for sale?

[Frankieola]

Got a car to sell which is only worth £900, Where is the best place for me to advertise it? I dont really want to spend anything so was thinking of Gumtree but also thinking of maybe Autotrader, Motors.co.uk, the local paper??!!!!!
Has anyone got any experience of what works best? Thanks

Your local Supermarket, Paper Shop, on the window of the car in bold Reflective paper, give the car its good selling points & be truthful otherwise you will come unstuck, give ALL the cars details Owners, MOT, Service history ( If there is one) if the car is on a main road put one on the OFF/S, Also the rear off/s of the window, + N/S for foot passengers to read.
