Ok, I could not find the number in the window but under the hood a number what I think is the vin was stamped in the aluminium car frame and on an aluminium plate fixed on the frame.
Although similar to the number listed on
InsightCentral.net - Encyclopedia - Honda VIN it is quite different and makes no sense to me:
HN-ZE1 was written on the first line and
ZE1-1000558 on the second line.
Any idea what all that means?
