Well, WELCOME!
As a relative new comer myself, I am not that far ahead of you. I for one think this would be a wonderful entry to start with in regards to where it is. My lessons-learned so far are that unless you get a fully finished, running car, you are going to want to basically do a full take-apart and start from there.
My saga has some of that shown as I struggled with how to handle my put-together car that had issues requiring a body-off approach.
While you want a Sterling or a Sebring, a Cimbria is not a bad option and is arguably more rare (windshield issues not withstanding) you could use it as a practice run and later sell it. You may also find that the gull-wing doors provide for easier ingress than the Sterling. The Sterling is like lifting yourself out of a bathtub and having to work your knees around the steering wheel. The Cimbria may actually have less interference with your knees.
Also, being watertight may be an issue. I have run into many here who say that getting a Sterling rain-proof-dry for driving is a challenge, not sure if the same is true for those gull-wing doors...
Otherwise, I imagine the principles between the two options are not that far apart and you may thus find very sound advice here.
Keep us posted on what you decide.
