turboned,
If the door is rubbing on things, it is probably not the frame having 'relaxed' but more a case of ovalising in the hinge pin holes...
I recently swapped all my Uno T's door hinges for the set off the back doors of a 1992 Uno 60S - naturally, they were mint, and even the right colour. You *can* get the hinge bolts out of the door pillar, with an 8mm hex bit and an 8mm ring spanner (an Allen key won't fit with the front wing in place). It only took a couple of hours and it makes such a difference having the doors close without crashing onto the striker.
Fine tuning of the refitted door can be carried out with the help of a trolley jack and a block of wood under the door bottom...
Hellcat - yes, I think your Tipo's door fit problem can probably be resolved with some careful heaving. I have, though, seen a number of Tipo doors that didn't fit very well (I think the build quality was up to the usual standards...) but the hinges don't seem to wear as often as on the Uno.
Using a carwash: having been to England a couple of times, I can confirm that in some parts of the country (no space, no hose, and metered water) it ends up being that a carwash is the only option (and still better than not washing the car at all... I have seen moss growing in cars that live outdoors!)
