My suggestion from your list? None. The Camry is a good car and so are the Benz but as mentioned earlier, your friend hasn't passed the bar yet. Yes, this is a car forum but we also keep a keen eye on values as we here at Tsikot.com considers everyone, including the TS as family, so we watch out for each other here.
So, as I was saying, if your friend is looking for a Euro car as a grad gift, I would suggest a
BMW 525i or
530d in
E34 or
E39 bodies. More or less in the Php1M mark. Also, I also strongly suggest to your friend that to ask for a car AFTER passing the bar exams. He/She will feel more fulfilled as well.
Hope this helps and welcome to Tsikot.com!
