I owned this RX4, twice - picked it up in a car yard, North Road Invercargill in 1986 with bugger all K's and one owner who was a heavy smoker (took ages to clean the inside and get the smell out). Came in Alexandrite Gold Metallic (awesome polished and in the sun) and was like a new one! In amazing shape and was a cool ride compared to the other cars I was looking at (Escort Sport and the like) with the wrap around dash and overhead console - so quiet and smooth, rev'ing to infinity and beyond.
Had some great times, trashed it as you do - upgraded to a stock 13B out of an RX5 (with the torque converter/manual 5 speed). When the kids started to show up it was sold (around 1989 or 90?) and picked up an RX3 sedan as the daily.
Shifted to Welly in 1991, and in the late 90's tracked it down again and made an offer (was sitting in a shed unused). The 13B was on the last legs and it was rolling on hotwires... A 'Peter Hopkin's' 13b stage 2 with an IDA, and some rust fixed around the door hinge and we were rolling again. Stock interior and paint, but someone had upgraded the front disc's. Sold it a couple of years later for $6,500 I think... big mistake, should have kept it in the shed. Enjoy!!
