I personally prefer the C class cabriolet because the car is longer, quieter, and has a better ride. The SLC is nice because of the retractable hardtop but it has a rough ride. The newer cabriolet soft tops are insulated very well and I don't notice a difference in ambient noise levels or interior temperature fluctuations. Now if you are only driving the SLC 43 for short distances and is a second vehicle, then it is a very fun and fast car. I would purchase the SLC if I were to only drive it once in a while and was looking for something sporty. I don't notice a difference between reliability or maintenance costs.
Right, the soft tops are actually made to last for the life of the vehicle now, barring any physical damage of course.
Both tops require periodic lubrication of the rubber seal contact points because they will get noisy as they rub together.
