'Making out'. I'm 63 and the fun I had making out in my assortment of junker cars BUT, I did get it on in the back seat of my dad's '68 Cadillac Coupe deVille with a buxom, very horny gf back in 1978 on a warm Miami night. She's still living there. Car sex is good dirty fun and I'd jump on it if I met a woman of any age who was game for it.
