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.)
* Napolean hat ... (Napoleon ist 1814 ins Exil gegangen.)
