We are waiting on delivery of a BMW 320i sports. Did the whole dilemma thing (I'm Catholic too lol).
Even read my husband an article about how a lot of the worlds richest men still drive their first car ie it really is just a waste of money. Anyway, we managed to get around some of the guilt by deciding it was a salary sacrifice necessity.
Oh and we don't have kids so that helps with justification and maybe we will take an orphan for a spin in it or something (the last bit was a joke!!).
