Condensation from your A/C comp.?
That's more than likely what the water is.
Oil sprayed? not sure. It may be from your Land Rover. Was she following you? JK
The burning/ rubber and hot plastic smell is normal for sure.
But if there is oil somwhere leaking you could be smelling that burning off the hot engine?
After things cool down in the engine bay, get a flashlight and see if you can spot anything leaking or puddled on the skid plate(s).
good luck, i hope it's just that new engine smell and she ran through some oil or something.
