Good rental experience

Excess human involvement. The process could be significantly more electronic or simplified. They had to shuffle through keys thrown in a draw for 5-10 minutes before discovering they didn't have the car model ordered so they provided a suitable but very different alternative.

The experience of renting through a rental broker and not directly from a rental company was a little uncomfortable at first (is this transaction legitimate/am I getting ripped off) but in the end the cost saving was worth the third party being involved in the process.

Car unusually old.

スバル　フォレスターまたは同等の車と言うことで、フォレスターでは無かったが、良い車だった。 カーナビゲーションが慣れなくて、使いづらかった（日本でも新しい車では同じことだが）。

Paying for additional driver was not expected

Like: The staff at pick up is friendly but staff at drop off is not friendly.
Dislike: I was told that cash is accepted at drop off counter, but then when I wanted to make cash payment over drop off counter, the staff told me only credit card is accepted.
