i see.. try modified insurance compaines, adrian flux ect as they normally offer good prices on these. kinda hard too answer for mileage as you can get cars with 40k miles on them that are in shit state and others with 100K and running perfect, it all comes down too service history ect, if your willing too drive auto you can pick them up much cheaper with less miles. i picked my Auto up for around the 3K mark with only 42K miles and then add around another £600 too convert it too manual. Be patience when buying one and keep reading around the forums too better understand the engines ect
