LOL!! Lovely, lovely shots!!
I remember the Citroen (the Lemon, literally) from Europe years back! Great car - had a friend who fitted it with a Porche motor and had to weigh it down with sandbags to get traction..lol.
Those shots are cool and very well done. Your lighting seems a bit yellow - if you went for that look on purpose, ignore me. Some LEDs or Halogen, a changed white balance setting or some post-processing might make your whites more white if that is your desire.
Love your images though! All we need is a small Tin Tin figure in there!
