My First Car - A few Questions

[Darragh]

Hi all!!

New to the forums. Spent a few days browsing about though. Im 21 years old and from Ireland.

I bought my first car a week ago. Its a 1998 Mercedes C180 Black. Since this is my first car let alone Mercedes , I have a load of questions.

Its hard not to notice that the key is not a key. Its more like a fob that I have to stick into the ignition. Is there any way of getting a spare key somehow?

Also, the alarm on the car is a little strange. I think I have to hold the armed buttton in and the windows wind up. Then when opening it, the unarm button opens the driver door, then press it again and the entire car opens. Could someone please explain to me how this works? I don't know if Im doing it right.

I got new tyres from the dealership that I bought the car off. So I was thinking of putting this chemical in them which makes them impossible to puncture. Has anyone ever used this stuff? Is it worth getting?

And finally, are driving schools any good? Im thinking about taking a few lessons.

Thanks,
Darragh
