Replacing the word nice in a sentence?

The best replacement for "nice" depends heavily on the context. To help me suggest alternatives, please provide the sentence you'd like to improve. For example, "That's a nice car" could be improved in many ways, depending on what you want to emphasize:

* If you want to emphasize pleasant appearance: "That's a *beautiful*, *stunning*, *elegant*, *attractive*, *lovely* car."

* If you want to emphasize quality: "That's a *fine*, *high-quality*, *excellent*, *superior* car."

* If you want to emphasize its positive impact: "That's a *practical*, *useful*, *reliable* car."

Give me the sentence, and I'll give you more specific and helpful suggestions.
