I found this driver on the forum here and I think he's worth his own post.
If you're looking for an incredible driver/guide while in Acapulco you can do no better than Cesar Olea Santos.
Initially, we hired him to drive us to and from the airport. After talking to him during the drive, he became our guide and companion for every single day/night we were there. He made all of our dinner reservations and even surprised us with a trip to a show/party outside of town that we would have never found without him (which, by the way, turned out to be the highlight of our vacation). He likes to say, "Nothing is impossible" and he proved it every day.
He speaks English very well and helped us as a translator in some unusual situations: Our friends ATM card was 'eaten' by a machine...he picked her up the next morning and drove her to the bank, explaining to the employees what had happened and retrieved her card.
I think the best way I can sum this up is to say, we started with a driver and ended up with a friend who I can't wait to see again.
A wonderful man.
