"I've followed a lot of build threads over the years and a distressing number just seem to run out of momentum. I didn't want to put anything up until it was my daily driver." So said PHer fattbutt, and that's exactly what he's done.
Rising from the ashes of his own inertia-affected build - involving a Rolls-Royce which became "more frustrating than fun" - this BMW Z4 makes use of the same 6.2-litre V8 LS3 motor as was intended for the stately Roller. A non-runner with plenty of existing problems, it's now a full-road legal super sleeper.
Concealing such an engine within the far smaller roadster presented fatbutt with a new series of challenges, of course, some of which took him weeks - or months - to complete. It's all laid out here in fantastic detail, including the not one, two or three but four MOT attempts which were required before the project passed.
It's rare to see a complete build detailed so well from start to finish in just one post, but it does at least eliminate the risk of any unresolved cliff-hangers. Those of us with the kind of residual trust issues stemming from years of emotional investment in unfinished projects and incomplete threads can get stuck into this one, then, safe in the knowledge that it has a happy ending.
