I had a 72 Datsun 510 wagon as my first car. Being a teenager, I spent much more attention to installing an underdash FM/cassette unit than the engine. It still ran like a top for a good two years. I sold it and the next week the guy wrapped it around a telephone pole. No one was hurt, luckily.
I could fill it up for $5.
Also the fold down seat was very handy on Saturday nights for . . . storing tools yeah that’s the ticket.
I had the same as my first NEW car. It was a great car. It only lasted 15 years before the floor on the passenger side started to rust out and the rubber hoses in the gas tank system started to deteriorate. It was time to sell it but I wish now I had kept it.
When it had 96K miles I ran my first & only autocross. The timer asked, "What do you have in that thing?"
"Stock 1600 engine with 96K, why?"
"You are in 3rd place, ahead of the Corvette!"
With 110K on the 510, I traded it for a '66 Alfa Giulia Sprint GT.
