second hand car

[changingsoon]

hiya

bought a second hand car from a dealer mid may. leaked oil withing a week had free diagnostic report done at landrover and dealer (with pressure agreed to put it all right). i went away for a week so he had time to do it all. seemed ok for a while, noticed monday oil is leaking again, and its much much worse, all over my drive!!!. What the hell should i do, i am a cm and cannot be without the car, my business will fold. dealer is an hour away so its hassle even getting there. have send really formal email and letter but he just does not reply. any help greatfully received x
