My classic (decidedly a non-sports car) is a 1968.5 Citroën DS-21 Pallas in white with black leather interior named Eponine. She is in slightly rough shape right now. A resto is definitely in order. I just haven't had the time to figure out the logistics of it.
I bought Eponine in the mid-1990s at 17. She was first car, and will be my last car.
Though I suppose my daily driver is getting on in years now too, and it is a bona fide sports car (2001 Mazda Miata SE, the one in BRG with a Nardi wood steering wheel and shift knob, tan leather seats, and tan canvas-look vinyl top). I'd actually love to replace it, but nothing else at any price feels like as much of a driver's car (including "NC" generation Miatas) except for the Lotus Elise. The thing that has kept me from buying an Elise is the difficulty of ingress/egress. The sills are huge, and I'm just too tall to do it gracefully. I have tried. I've test-driven Elises several times with intent to buy.
As for vintage audio equipment, not really. Unless 1990s-era separate magnet, Tulip-waveguide Tannoy Dual Concentrics count.
