As Peter says, the Tecnam is fairly useless for touring. A useful load of 400 kg means you'll never be able to carry 4 adults anywhere, indeed 3 with fuel will be a challenge.
140 knots is too slow for a twin IFR tourer. You may not be burning much gas but you are travelling at single engine speeds. And the range is dreadful.
Also the limiting speed for the gear is 90kts. Try flying an approach into any reasonably busy airfield at under 90 knots and I'd take a book to read while your being held.
I'm sure it's a good training aircraft for schools but for hard IFR it's just not suitable.
