1970-1980 Chevy K10
It's a truck, sure, but it's my dream vehicle* and also, I already own it.
Here is mine:

Do note the average vehicle MPG today is less than double of that from the 70s. With that said, vehicles from the 70s, again, on average, had a lot more power than most average vehicles today. My 74 gets about 10 MPG compared to a modern pickup which averages to 20. BUT, mine hauls a lot more ***.
TLDR: Less MPG, sure, but a lot more power on average.
