I have 2 XMOD Landy's (1986 90 and a 1987 110 5k miles on a new rebuilt engine), I just finished a trip in early December in my 90 (ex Cyprus 62K on the clock, with original engine), 4500KM from the UK to Romania, with multiple areas in between. Avg'd around 28mpg for the entire trip. Had to replace the starter in Holland and oil sump gasket and rear seal in Romania, wasn't the fastest, but it drove fine, the hills were somewhat of an issue, but got going fast down them, that helped on the next one, most of the time had to go down to 3rd for Austria etc, but on the straight aways hit 60-65 mph with no issues. My 110 is going to get a 200 tdi put in it this spring, will use that for towing and as an excursion vehicle, the 90 I want to keep as is, just to drive around the hills, short trips etc. just purchased all new PAS parts to put on it so parking in the cities will be a lot easier backing into tight places. I also chose 2 soft tops, just love the sides rolled up, retro fitted a Rad/Haz kit in my 90 and it is a world of difference in noise and temp.
Lucifus-your 110 looks great..
110 engine rebuild and original 90
