My 1501 is 1970. Learnt at the international Simca meet that 1970 is the best year for any Simca.
The other wagon is 1974 I think. I'll have to check my spreadsheet when I get home.
EDIT: It's 1971, the other 1501 wagon. Currently I know of 12 Simcas on the road in New Zealand and am looking to expand that number.
