For the 156, you have 3 options:
Ordinary manual, available with TS/JTS (5 speed) or V6 (6 speed), or even diesel if you can find one. Nothing to report here - just the usual clutch slave cylinder failure every so often, clutches themselves don't usually go past 200,000km. Be aware that on the TS/JTS the clutch slave is a concentric type fitted inside the bell housing so it's a gearbox off job to fix. The diff on the 3.2 V6 is weak.
Selespeed, available on TS/JTS and 3.2 V6 (GTA) (very rare) - the same gearbox and clutch as above (pretty much) but with electro-hydraulic actuation of clutch and gear change. More to go wrong. Generally the hydraulic actuator needs replacement at somewhere around 120,000km. There's a place in Auckland that refurbishes them but you're still looking at somewhere over a grand to repair. Has a 'full auto' mode called city, kind of works ok.
Q-system, available on 2.5 V6 only. Ordinary 4 speed automatic, it's a Japanese Aisin box and they usually don't go wrong. No flappy paddles but has an unusual H-pattern gate for manual changes.
I have a selespeed and a Q-system. The sele is much nicer to drive.
