I was impressed the way this old machine cruised along, would cruise anywhere from 80 to 110 comfortably on the flat. The machine has 7:50 tyres (Seems slightly overgeared), gives an under read of the speedo of about 8% compared with a gps.
 
    Did 1,712 K's in 2 days, fuel consumption varied from 5.5 K's/Litre at 110KPH with a headwind to just on 7K's/Litre sitting on between 85 and 90 KPH.
 
    I have a couple of questions to those in the know,
What does a standard series one tank hold? 
Standard tank is 45l - but I am not certain the 107 wagon has the same.
Is the overdrive when engaged supposed to be louder (Howling noise) than forth gear?
Not really, but they usually are - can get very noisy without being on the brink of failure
How is the fuel consumption, is that what to expect?
About what I would expect - see below
What highway speed do other people sit on? 85 to 90 seemed most comfortable.
I would agree with about 90 being comfortable
What size tyres would suit this set up? 
 Original would have had 7.00x16, but with the larger engine, 7.50s may be more suitable, particularly since 7.00s are unobtainable, although these will be responsible for about half of the speedo error, probably an increased turning circle, and slightly heavier steering.
    I nearly sold this old machine a while ago, glad I didn't. I'm looking forward to getting out and about with it.
			
		 
	 
 You have a vehicle that is mechanically a Series 3, but it has the somewhat less streamlined Series 1 body, which will make it a little slower, thirstier, and more difficult to drive, although I suspect it is a bit lighter. But it has a lot more character than the later wagons!  Sounds very interesting - pictures?
