haha eventually all CKD have issues, go for a test drive and you will know which to choose

Haha seriously you need a test drive to get the feeling of both cars, all cars eventually for issue but you get warranty.

Service wise W205 is expensive if you dont bugged your SA for service vouchers.
F30 get 5 years included which is good.

Interior wise W205 is much better, handling wise F30 is much better. It really depends what you focus and need really.

haha afterall just go for the one you like more, no regrets
