I know when to use sein and when to use haben for the present perfect. My muscle memory doesn't always agree with me on that point, though, which results in my starting a lot of sentences with ich habe, and then realising that I should have said ich bin. Starting anew is awkward, and I don't want it to look like I don't know the difference.

Until I've taught my subconscious to use the right auxiliary verb: Are there other verbs that can be used to save the following sentences, resulting in approximately the same meaning?

• Wir haben ... (Wir sind letzte Woche nach Deutschland gefahren)
• Ich habe ... (Ich bin in der Stadt gewesen.)
• Er hat ... (Er ist gestern angekommen.)
• Napoleon hat ... (Napoleon ist 1814 ins Exil gegangen.)
