@ surely-not.
I believe that ARV's are classified as "orphaned" now and are looked after under the excellent custodianship of the LAA's PtF system .
The chap I share my hangar with had one for years , it was a really nice little machine and his was powered by a Rotax 912 , although I'm sure a suitably engined Jabiru would have also been a good combination.
I haven't seen one with the original Hewland engine for years and assume that most of them have been re-engined .
Airframe-wise they were as solid as a rock .
When they came out , I think it was hoped that they could knock the C.152's crown off as a trainer . But I believe its Hewland 2-stroke was its Achilles' heel .
