but see, you're not being fair to the question. i'm not asking for justification. i'm asking why you want trash cars. it's no different than asking why your favorite food is what it might ever be. there's no judgement in my asking. i'm just trying to understand, you know, to get to know you. maybe you'll have a strong reason for it that convinces me to want trash cars in my yard too. but you'll never know because you take this immediate position of justification and non-answers

Not OP, but given enough time/money/land I'd probably have a dozen or so old trash cars on my property. It's fun to fix things, including buying a couple wrecked donor cars in order to (attempt to) build up one working one. It's one of my hobbies, although I don't have the time/money or room to go all out.

there's a difference between a parts car and a trash car. parts car implies what you are saying that there's a project car somewhere. trash car implies something else entirely.
