First car was a datsun 100A, K-reg (suffix) Learned to do most everything on that car.
first job was to drop the gearbox - it was like stirring porridge.
Engine was immaculate - despite high mileage.
First new car was a datsun stanza, 1983, A reg (prefix). that was on the cusp of the name change. It had a datsun badge on the grille & I was offered a new Nissan badge as a replacement. I accepted the new badge but put it on the grille alongside the datsun badge (same on the rear).
Also given another badge to mark ??years (I thought it was 50).
Had a choice, either the ford sierra or the Stanza. Similarly priced, same size cars - but poles apart in terms of spec. The datsun included radio/cassette as standard (nothing in the sierra!), mudflaps, intermittent wash/wipe (with 6 intermittent settings in 2 sec increments), lights on alarm, eye level brake light, 5spd gearbox, bulb failure warning on dash, seatbelt warning, tailgate & fuel flap release lever by driver's seat, low washer bottle fluid warning, rear screen wash/wiper, colour coded carpets, carpet mats, powered vent shutoff system (each outlet set had its own control flap - rear footwell, rear body, front footwell, front body, screen, front door glass - any combo selected via switches and electric flaps (not just a rotary dial with a few factory options), tinted windscreen with sunstrip (choice of blue or green tinge, fading in to heavier tint for sunstrip).
Got a decent price for PXing my old car as a discount.
