Even from 6,000 miles hence, you can't keep me away from a bit of conveyance discussion. The main thing to remember with conversions on "odd" cars such as Messerschmitt's is that there are many disablitys which can stop you walking any distance but which can still leave you with enough use of the legs to be able to get into, & operate foot controls, in the normal way. Trouble is, this ability to get into a car such as a Messerschmitt might indeed mean you do not QUITE qulify for a Ministry conveyance, hence why they bought a Messerschmitt, Scootacar or Trojan. Before anyone starts on about "why didn't they then get a normal car?", remember also the tax advantages etc that bubblecars had over normal cars, not to mention their ease of manoverability & fitting into gaps etc. This I would say is why there are several disabled conversions on bubblecars.
Sounds like an intresting edition of Take Off awaits me when I get home.....
