As a new car salesman, my Dad didn't own many cars as he was always provided with a new car demonstrator.
Of all the demo cars he had, his Lucerne Blue 1970 T/A 4Spd (the very first T/A to hit my home town) was my favorite.
But to answer the actual question "What was your favorite car that your dad
owned?" the answer is...
This car that I restored in the mid 90's (after being parked for 30 years) so that I could see my Dad drive it again!!!
Dad bought it in 1958 - it was the "perfect" family car for a family of 10. It's a 1949 Cadillac Series 75 Limo...
