The Senecas compared to other older twins should fair better as the majority of parts are still readily available from the manufacturer!
Seneca parts are also the ford escort parts rather than the Mercedes cost parts of Beech Barons.
As twins go they should be cheaper to maintain than others although none are cheap and 18 to 20 K is pretty normal for an annual check regardless of the twin manufacturer!
Ok you have a turbo but then again I would not consider a twin without one regardless of make! I have flown Senecas at 20 K plus where you will get 210 to 220 kts TAS
Down low 160 to 170 kts TAS
The Seneca will maintain 16000 feet on one engine try that in a normally aspirated Beech Baron over high mountains at night!
