Have you calculated how much money you'd be getting out of the sale and how much your downgrade would cost?
Not saying you shouldn't downgrade, just asking if you've done the math to see what kind of money we're talking here.
PS - I drove a newish nissan versa. Well, I drove a hatchback that was utterly horrible, but I drove a newer sedan too. Really fun car. Tiny engine, but also weighs nothing, and corners like a pro. Empty roads around Mount St Helens made for a very fun drive. My car corners better but it's much heavier and feels like it'll slip, whereas this car just felt really zippy. It's the only small car I've driven (out of 10+) that I enjoyed. This is not on topic, just felt like sharing.
