Why do you wear sacred garments?
You'll get abs if you lower your body fat % by losing weight (through a calorie deficit) and strength train. Diet has nothing to do with it. You have to lose all your abdominal fat. If you eat too little you'll be sacrificing a lot of lean muscle which will be counterproductive. So I highly recommend you aim to lose slowly; 1/2 lb per week since you're already a healthy weight.
The good news is that your vehicle already has some electronic traction aids such as ABS, ESP (electronic stability program), and BAS (brake assist) to help you get through whatever you encounter. The bad news is that even with all those aids on your C230, the amount of traction your vehicle has ultimately comes down the only part of the vehicle that come in contact with the roadyour tires. The term all-season doesn't describe the tires very well because an all-season tire is in reality a compromise made between summer and winter tires. For best traction in the winter time, you need a full set of 4 winter tires.
A moisture detector, aka leak alarm is a relatively new device. A basement would be a likely place to find one. When the battery gets low, it sounds exactly like a smoke alarm chirping. They look like a plastic box, roughly 3 x 4 x 2. Until you know where it is, it can be maddeningly difficult to find one just from the intermittent beep. Look first in the most likely places for a leak to develop, water heater, sink drain, sump pump, etc. Good Luck
