Enjoy your car. Hoping the knocking noise is in the suspension and not the engine. The trailing arms have a tendency to give a thumping noise when you hit a bump they could be a place to start looking.

Yeah knocking seems to be suspension not engine. Dont know if its anything I can fix myself or not .. prob not

Also getting a tinny rattle on idle now too ..had a look underneath and it seems to be some metal cover that's around some pipe related to the exhaust that's vibrating...I prodded it with a stick and it stopped making the noise .
