My friend can be quite snobby at times ... we have been friends since childhood and it's just one of her little quirks.
Such as when I bought my first house I asked her if she would like to stay over and she said yes only if it was clean.
Anyway we meet up once/twice a month and have always taken it in turns to be the one who drives. She has been given a new company car (a few months ago now) and it's a nice car - much nice than mine anyway.
I have noticed that since she got it she has always turned down my offer of driving when it's my turn.
Such as I'll say - pick you up at 8 and she'll text back saying no don't worry I'll drive.
Or if I insist that it's only fair if I drive this time, she'll say I've got really bad car sickness and I only feel ok if I'm driving.
I've known her 20years+ and she has never complained about having car sickness before.
Her car is nice and mine is a very boring practical estate car but I just feel a bit hurt and embarrassed that it's not good enough for her.
