I have seen some of those cars! lol
My W124 will be 20 next year and you can have a new born crawl all over the interior without fear of catching some kind of flesh eating bacteria lol
I see C classes that have been on the road less than 5 years and they look really disgusting. Also some people really are slobs inside their cars...
for crying out load clean the soda (coffee or what ever) spill before it dries, collects garbage and turns your cup holder and surrounding console into a huge petri dish of sticky smelly bacteria....uuugh!
If some people literally live inside their car then what do their houses look like? Yuuuuuck.
