I started off with a 1990 Ford Fiesta 1.1L, it was a complete shed and i rebuilt half the car during the summer before my 17th birthday. Of course the rust re-appeared within a year but i didn't care! The engine threw a rod @ 90k miles. Sorry no pictures at hand
Favourite has to be my current 854 T5 with my MX-5 fighting for second place. The Volvo just does everything so well
