Is the inside of the V40 exhaust pipe black, like soot? Could it be too much carbon buildup?

I'm considering getting the T8 Black Edition 4WD diesel. Could fellow car enthusiasts share their opinions on this vehicle? What's it like?

Have any fellow car enthusiasts encountered a situation where the catalytic converter has minor cracks, causing occasional exhaust emissions to go uncatalyzed and triggering the emission warning light?

Hey everyone, I've got an issue with my 09 model. Sometimes while driving, there's a sharp "dang dang" sound coming from underneath the car. It comes and goes, and sometimes I can even hear it when idling. The repair shop mentioned it might be the exhaust pipe but then said it doesn't seem like it. They think it might be coming from the bottom of the engine. Have any of you experienced something similar?

Is the two-door version of the Jeep Wrangler worth buying if I'm traveling solo across the country at 36, without carrying too much luggage and not planning to go off-road? Just asking fellow car enthusiasts if this car is worth it or if there are better recommendations. I don't like large or long vehicles.

Has anyone experienced water leaking onto the passenger side from the AC? The AC drain pipe isn't clogged and it's draining water. Could it be that there's water inside the evaporator box?

When driving the Tiida, there's always a rolling sound like a water bottle moving back and forth, but there aren't any bottles with liquid inside the car. What could be causing this?

Why does it feel like everyone online is criticizing it, saying it's not good and not as good as the 700-500, yet its sales are so high? Are the people who buy this car just not smart and have too much money? [facepalm]
