Thanks for the information!!

I'll go into a Mercedes dealership and find out about getting a spare key made then.

I took it for its first big drive yesterday. Even drove it through an industrial estate where the road was more like a dirt track. It handles corners and bumps really well. Very comfortable. I noticed that it doesn't like being in low RMP while in high gears. It gets a bit shuddery. But this is probably normal right?

Well I booked my first driving lesson. Hopefully I'll pick up some good habits from it. If I like the guy I'll block book a few lessons.
