A nice home, as I would only enjoy the garden for the warm part of the year. Garden would be second, and I'm not really bothered about cars, as long as it gets me from a to b and doesn't keep breaking down. But I am a woman - my hubby might say otherwise. I reckon he'd put the car before the garden, and maybe even the house!
A nice garden can bring you a lot of happiness- not just growing things, which is a bonus, but spending time dead heading and trimming things back as well as a nice lawn can all have huge benefits on your life.
