Funnily enough I did see a couple of Commandos in Spain, both Jeepster Commandos and both sporting diesel motors, 4 cylinders I presume. One belonged to a German younger man, who spoke little Spanish or English, so I didn't get much info. This was in the town of Javea, at the Lidl (German) supermarket. The vehicle had no top or roll bar, but seemed to be in pretty good shape.
The other was in a rural area on the plains of La Mancha in a sunflower planted field, putting along and being driven by an older gentleman. I presumed diesel as there was a plume of black exhaust trailing behind it.
I also saw several restored flat fender CJ's and MJ's, all seemed to have 4 cylinder diesels. One in particular was a perfect restoration of an MJ, complete with all insignia, shovel, axe and military type antenna. This was in the small pueblo of Murla, situated in the Jalon valley. The other flat fenders were seen regularly in Javea, one even being offered for sale at a price of 4K Euros. Jeeps command very high prices in Spain.
