I've just MOTed the Z300S for the 8th time. Just like the TFS last week, failed on emissions until the test rig was reset, then- no problem.
Afterwards I went to a mate's business just round the corner- he "electrifies" cars usually retaining all of the original chassis, etc but substituting motor(s) and battery packs. He had a nice selection in- E-Types, Beetles, a Porsche 365 cabrio, a 911, DeLorean, Stag, etc. Also a nice early Mini with a 150bhp motor- goes well apparently. Also working on a TVR track day car aiming for 0-60 in <4 seconds.
He has a silver Z3 2.2 with 200k, not intending to convert it, "some" lights on the dashboard and no MOT which he'd like to move on...
