Welcome!!!...Buying this bike qualifies you for the nickname, "CHROMEHEAD!"
Back in the 1990s, there was a movement in the cycling world to re-capture the vintage motorcycle experience/appearance but provide better safety, performance, and reliability. Honda did it with their Shadow ACE (American Classic Edition) models, and other makes made similar attempts. Back then, I bought a 1995 Honda VT1100c2 Shadow ACE and enjoyed it for nearly two decades before upgrading to my 2011 BMW R1200RT.
The BMW R1200C (CL) series was BMW's effort to tap into the cruiser craze. Although, BMW's distinct boxer engine and suspension arrangements make its BMW DNA very difficult to associate with any "classic" image. However, for me, a collector of Studebaker vehicles, (who once had an advertising slogan of "Different by Design")...the very unique R1200C bikes is what caught my attention and ignited my desire to abandon my old Honda classic and begin my search for a BMW.
During my six month search, I looked at quite a number of "C" bikes and expanded to other BMW models before finally settling on an RT. If I find a "C" for the price I'm willing to pay (not too much), I will still buy one. As you are finding out, except for certain models, the "C" bikes are rather "spartan" in their instrumentation. Also, even though the engine is a 1200, it is way down on hp compared to other period BMW boxer and K engine powered bikes. That's not a deal killer, but worth noting. I was also alarmed at how many of the "C" bikes have ABS problems??? You have a 2003, which is a plus. By then, some of the common nagging problems such as flaking chrome, and cracking tail light housings/brackets had been addressed.
I'm 74 years old and buying my RT with its adjustable windshield, cruise control, tachometer, gas gauge, and all the other stuff
at near the price some folks were/are asking for these "C" bikes made the decision easy for me. Depending on your riding experience, and desires...I think you will have a wonderful time getting this bike roadworthy, tinkering with it, and riding it. I hope you stick around and share the journey with us. In addition, there is a dedicated forum for the chromehead bikes,

I am a member there and I think you will find it very helpful in your quest to get your bike where it needs to be.
