when do I leave a buyers review

well, who is going to frequent this affair~ have been searching for another 610 wagon, white interior w/ aqua and phony wood~ 1973 was a very good year~ cargurus does not even accept that as one of the choices~ but one must think WHO is going to read this? finding that Google reviews are often misinterpreted, and forcedly one sided~ one to five stars seems unfair, what if the unit worked then failed~ what then? zero? Google has it's own bit of quicksand for you~ also collector's clubs of your car, the Datsun B-210 has a club, and NOT one of their best, but did work okay~ right now we must think silent electric one could electrify a squareback for 4000 dollars~
