In the 70s and early 80s, my dad had a succession of 60's Singers, Cortinas, Rovers, and Austin/Morris (Landcrab/Wolseley 6) and later a Chryler 180 and Vaux VX4/90 as cheap bangers and they smelled nice inside, even if they didn't go that well and seemed so much nicer than
80s cars. Then when my mum started her own wedding business and bought an 3.4 S-Type Jag as a Wedding car it was that sealed it, it was fairly reliable, sounded loverly, wasn't rotten, went quickly, and had that smell.Became a regular practical classics reader since that time, right until the late mid noughties, and since I passed my test, back in 2001 (didn't need a car of my own until I was over 30) every one of my cars bar two have been a least 15 if not 20 years+ old. Simpler, easy to work, and all had the old car smell in one form or another.
