new terrano11 owner

Hi all. Had the car ( black over silver, manual 3.0 sve diesel, 7 seats, 74k) for a couple of weeks and so far so good.
Reason for purchase was ssangyong musso with two extra seats too small for the kids!
The car is in great nick with great tints and the cleanest wheels (like new) iv'e seen.
Couple of things, the engine pulls like a train but seems to me very noisy, like a black london cab, until warm and then like a warm black london cab. Is it normal, will i get used to it?
We'll see.
Secondly, only one key with the usual remote problem. Looks like a fingernail has punctured the rubber and it is a little tempremental as a result. Any ideas? Sorry if this is a recurring question.
Lastly digital dash been replaced, but yesterday the trip and clock reset themselves for no reason.
Mostly I'm chuffed with it.
Thanks in anticipation. Enjoy the snow!!!!!!!!!!!!
