R-19 (f)

So hello for now! I’m new here in the forum. I’ve already looked at some accessories and I’ve already learned a lot about them. I recently made my driver’s license and have hardly any idea of my car. I drive a r 19 (f) X53 already my question about what the X53 means to me in the vehicle ticket in the 3rd line. I also have my 73 ps wants more! preferably much more I want to ask for a corresponding engine, which is already so his na I say m al 160 – 180 ps. if one of the prices of the engine and the installation costs could have cost me that quite nice. so the first thing in advance. I think that will still follow questions but that should be enough for now. mfg your Stoerfgloewer
