Thanks Jason but is this correct:

Well, I ran my little 'experiment' today. Taking into account the 'instrument'
 I used is just a $5 clip on digital vent thermometer from ebay, so it won't be the most accurate I know, but to give an idea of extreme difference in air-conditioning temperature output I think its enough for the purpose.
My vehicle is a MY12 90 Puma with the standard rubber floor and seatbox mats, no other insulation (yet). the car has all windows tinted, except front of course. I clipped the 'instrument' onto the fixed vent on the drivers side of the clock. The air-conditioning was switched on with no fan assistance added, set on recirculate and the vent dial was set to just the upper vents only for this 'experiment'. During the test the ambient air temp was between 23 and 24.5 deg c. When I started at 10.55am, the temp in the car was 21.9c. I then drove along the highway (100 kph area) where the aircon temp dropped to the lowest of 0.4c at 11.13am, from here it began to slowly rise to 8.3c at 11.25am when I reached by destination 33 kms from where I started. At 12.56pm I resumed my test the aircon temp showing 8.1c after driving a short time. Once again I was travelling at 100 kph. At 1.14pm the aircon reached its lowest temp of 0.7c. I travelled about 60 kms this leg and at 1.34pm the aircon temp had risen to 9.2c. I then drove around a 50 kph area until 1.39pm and the temp had risen to 11.1c. I returned to driving at 100 kph and travelled home (about 26 kms) and upon arriving at 2.06pm the aircon temp had risen to 14.1c. Once parked in the garage the overflow/dripping from the aircon unit didn't start for about 10 to 15 minutes. While driving you can definitely feel the heat coming from the seatbox/tunnel area after a while, I think I can actually feel the heat permeating up through the seat cushion ..... No doubt this does add to the cabin temperature but I would have thought an efficient air-conditioning system would overcome this. Bearing in mind the outside temp was only 23 to 24.5c as well  in my recent vehicles in this type of temperature I would actually be warming the aircon temp up a little.
I also noted that the aircon compressor in the engine bay, the pipe that comes from the back of it there is a blue cap on a fill/empty valve. Between here and the silver insulation when the aircon is on for a short time this pipe is cold to touch, at the end of my 'experiment' today this portion of pipe was hot to touch, the other side of the insulation just prior to entering the bulkhead the pipe was cold but not ICE cold. Well no doubt all of this means jack...t but I said I would post my results on AULRO and thought you guys might be interested, maybe not. I WILL in the near future insulate the vehicle and hope for better results from this meagre aircon. Sorry for the long winded post

Thanks for the info. So to make a long story short, the solution is insulation! Or a D4.......

Here today overcast and "cool" at 25°C ... so no blazing sun and had to turn airco down from highest setting!
Guess time to source some insulation/sound proofing and solar film for the windows. |

I think you're all on the money with improvement ideas, but at the end of the day when the sun is hot its 50C and you can fry an egg on the road bigger/powerful aircon would fit the bill.
