Yes, I know you don’t expect to see "car rental" and "quality" in the same sentence.  They’re typically not much different than airlines, where you’re just a nuciance they have to deal with to get revenues.

Well this one is different (sorry for sounding like an advertiser, but they really are different):  Silvercar

As of today they’re in 8 major cities, and I expect they’ll continue to grow.  They only have 1 type of vehicle … an Audi A4.  And one color … silver.

So you know what you’re going to get, every time.  And it has GPS and Sirrus XM at no extra cost.  Nice car that is large enough, powerful enough, and with a good suspension system.

They have both iPhone and Android apps, and you simply scan a QR code and drive away.
