With Mexican things it's impossible to know the year without decoding the chassis number. There were many configurations. Big & small lights on the rear were of your choice, rear air intake pods were dependent on the environment on which they were to be used, RHD (182) & LHD (181) were made side by side,... The list goes on & on.
Either way, this particular 182 looks unmolested & well worth saving. I hope you get it, once you do, you'll forget about all other VWs. They are so versatile & fun to drive. Once I got mine on the road, I completely forgot about my 1303 (even though it's an amazing vehicle to drive too).
Everyone should drive/own a thing at least once!
