Well comically, if I ever needed car advice, I'm asking my sister not my brother. He thinks with his wallet she thinks with her head.
I grew up the middle child, brother was the super jock multiple girl friends older brother that everyone expected me to copy.
My sister was not on the cheer leading squad, but hell they'd have been grateful to have her.
Dad was Ward Cleaver, mom was June. Let me tell you, I grew up surrounded by cliches that were most assuredly real

My school friends all got cars. One chap, he was always on about someone hit his car and so he had to beat him up. I figured he had to have beaten up half the town.
But I had no need to cruise, I wasn't driven to pick up girls and be seen as 'manly'. I spent my teens in a library. It's why I am a walking encyclopedia, but I have so little in the way of 'street smarts'. I missed out on the male AND female developmental experiences of youth.
My early 20s was spenting drinking with a gal buddy. We danced, and hung out, I had no troubles dancing with her and numerous unattended girls on the dance floor as is often the case as so many guys suck at dancing or they are shy about asking a girl to dance or both I suppose. Shy? I have no idea what it feels like. I wanted to dance, and if it meant dancing with all the girls on the dance floor well, I suppose I know what a lot of gay males know

I actually find a lot of that sort of humour funny. Be wary of a girl's gay friends

I fit in easily with girl based activities.
Super Bowl party? Nah, too much grunting. Tupperware party, now that's my sort of fun.
It's not that girls don't know car maintenance, but it's rough on your hands, hard on the nails, and it's messy gets in your hair and leaves smells of grease. It's at least not hard to wash off saw dust.
As for fitness, well I must admit, it is fun listening to my sister laugh about running her cop and fire fighter buddies into the ground on a squash court

She's 50 and looks better than most do at 25.
I have a secret wish, to some day show up in a decent wig, nice make up, and wearing something attractive and laughing with my sister that at least now she won't hate being told she looks like me

Last comment, I DO spend aggressively, but, the household concerns trump fun stuff. I have plenty of money in the house, but, it is spoken for. Food money is not accessible for non food needs, and I divide my pension at day one, and each week gets funds reserved for it. I am fairly methodical. When I say I am broke, it is only Lesley's allowance that is gone
