Is this normal, or am I really that sick?

Underpowered vehicles aren't really my thing but I don't think you're weird for enjoying yours. If I was going to own a "slow" car it would probably be an 80s-90s Mercedes diesel; slow but excellent fuel economy for its size, great build quality and comfy. If I did get a slant-6 car it would definitely be an earlier A-body with manual transmission but I think eventually I'd swap a 318 into it. Who knows I'm only in my 30s, people say you slow down when you get older but my grandpa (who I'm a spitting image of) was a speed demon all the way up until he couldn't drive anymore lol. My dad drives with a feather-foot and it always drove me nuts lol.
