Have to say... really enjoyed #1 and #3 (still reading #2).
My experience of an Iceland car safari was great too... albeit ruining the tracking on the rental Suzuki was a bit disconcerting, as was losing control of the transmission after fording a river (turned out one needs to be stopped to engage low gear, and then the “reset” was on pp 374 of the 546 page manual - and not in the index...).
