What is there to handle? Enjoy your car, let her feel about it how she wants. Assuming you can afford it, and you want to use it, it makes sense for you to have it, and apparently it's there if she wants to use it too but she says she doesn't.

Don't expect her to act happy about it. Based on what she said, you can be pretty sure she'll act like she does NOT like it. You didn't buy it for her, you bought it to do things you want to do.

I think though that buying a car that you wanted and she didn't is going to weaken your argument against spending money on home repairs that she wants and you don't.
