Ever just want to walk away from the old car thing?

Just can't get into it lately, for years I've spent every available penny and huge amounts of time on my car. And still when I drive it, it's like, it's OK, but still not what I want it to be. Needs more power, or its too loud, or this still rattles,etc.
I'd like to do some big money things to it, like build a better engine, ad a gearvendors, or fuel injection. But don't really have money for that, and just don't ever feel like working on the car.
Just frustrating not being able to do the things that will make it more fun to drive.
Maybe I'm just getting to old and used to the comforts on newer cars.
