Q:

What does 让 mean in 我不但能够让外国人坐我的车，还能够让他包我的车?

In the following sentence:

我不但能够让外国人坐我的车，还能够让他包我的车。

This is from a Chinese reader.  The voice is of a Chinese taxi-driver.  
The problem is the translation of 让...
He's talking about going to hotels and getting customers.
Does 让 here mean, I can get them to take a ride in my taxi and also I can get them to hire my taxi (as in for several hours).
Or does it mean 'offer' as that seems to be one of the meanings of 让 given in the dictionary.

A:

Does 让 here mean, I can get them to take a ride in my taxi and also I
  can get them to hire my taxi (as in for several hours).

Yes, you are right. In this case, the taxi driver is boasting his ability to persuade foreigners to ride in his cab and to even hire it for exclusive use over a period of time.
According to 汉典, 让(ràng  ㄖㄤˋ) has the following meanings
　1. 不争，尽（jǐn）着旁人：～步。～位。谦～。 (yield, give up)
　2. 请：～茶。 (offer)
　3. 许，使：不～他来。 (make, get)
　4. 任凭：～他闹去。 (let, allow)
　5. 被：～雨淋了。 (indicates passive voice)
　6. 索取一定代价，把东西给人：出～。转（zhuǎn ）～。(trade)
　7. 闪避：～开。当仁不～。 (excuse)
　8. 责备，谴责：“二世使人～章邯”。
　9. 古同“攘”，侵夺。
From the context given, the taxi driver is certainly not boasting about offering a free ride to foreigners but his glib of tongue in getting (使, the third meaning) them to hire his service.
