Andy I think you need to bolt a spare wheel on the boot lid of the trailer just like Snatch
Another evening's progress saw an initial install of the roof panel -
..obviously I'll have to wait until we get it into the wind-tunnel for the final figure, but I'm expecting a drag coefficient of somewhere around 1.
I'm affraid the Drag Coefficient will be higher than 1 Andy, more like 2.1

OMG!!!
Cd= 0.41 i did not expect to see such a low value, it's even less then Opel/vauxhall Calibra which is know to be the best design of that era with results of 0.56
I didn't realise there was even anything good about a Calibra...!

If this applies (and all the other cars seem of a similar vintage... -- but just look at the fantastic figure for the Uno!) to our beloved "rectangular box"-style Pandas, then it's not brilliant to begin with.... (Confirmed by this page -- using Betty as my exemplar....)
Having said that, who cares? Their small frontal area -- only beaten by a 2CV and Suzuki Alto(?!) -- makes them streamlined boxes of joy...!
Thanks for the suggestion Jacob, it may come to that if my plans for rubber and stuff, fails. But then there's always a towel.Andy, i wastotaly unaware that your plan is to have caravan trailer. Well thought, keep on with the progress not much time left. Regards how to seal all gaps and connections my initial thought was to use fabric from old kite or parachute fabric- less then £10 for 5x 1.5m of ebay. Fitt number of eyelets like in tarpaulin and tied it down like a tent.
Interestingly enough one of the worst things aerodynamically you can have on a car is a gutter rail around the the roof of the car - The bit that used to be used to spot weld the roof on, as is common on minis, VW Campers, old land rovers, etc. The gutter rail over the wind screen splits the airflow creating a massive vortex over the roof of the car, this is dragged along with the car and effectively doubles the frontal area.
Back on topic - Good job with the trailer.
Back off topic - I quite like calibras...
On gutters, I read somewhere recently that the Uno was credited as being the first car to do away with them. Is that right or do Pandas pre-date Unos and qualify as gutterless?
I might be interested in passenger doors, let say 6 inches around where mirror goes on.
... if possible of course.
Mine outer doors skiin rested thru just below where mirror meets weather seal
