Hey everyone,

Thanks for your replies, they are super helpful. I come form a BMW family (E30, E36,E85, 2xE53's), which is why I'm partial to BMW's and their drive.

I'm aware that things will break and I should budget for them, which is why I'm looking for a used one, I'm fully prepared to spend money on repairs.

My friend made a good point about the emissions, he said if I'm just concerned about the gas mileage (which I am), then just go for the petrol version. If you have to deal with emissions, then that will set you back way more than the savings of the fuel.

My wife also commented that she wouldn't want the "louder" sounding diesel engine and she would rather have a quieter ride.

I think we're going to go with a petrol version. Thanks for your comments and insight everyone.
