My first drive was a 1964 Chrysler New Yorker. It was big and comfortable. I called it the Yacht because that's what it felt like trying to park it sometimes. But I felt safe driving it! (This was in 1980-1981, when there were a lot of little Hondas and Toyotas on the road).
No one's mentioned my first car yet -
'66 Pontiac Le Mans convertible, midnight blue with a white top! It was a boat, and hard to keep under 50 mph. About 8 miles per gallon, and I remember the first time that it took more than $5.00 to fill the tank! What a shock!
