Selespeed is a manual gearbox and regular clutch, controlled by hydraulics. Even in 'CITY' mode it isn't what I would describe as 'full auto' (for instance, there is no creep). Make sure you're happy with how it drives. If it is juddery and difficult to drive smoothly, start talking down the price, talk about a new clutch and release bearing being needed (even though it's often a simple job with Alfadiag to fix it!)
I think with an older car its better to go for a manual instead of a Selespeed but you'll probably get plenty Selespeed owners telling you the opposite
You're probably right, but with 238,000km on the clock, my Selespeed seems reliable
Though I've only done 2000km of those. Still, I have faith in my Selespeed. It's much simpler than an auto would be... and much more economical.
I sometimes wonder whether the 2002-onwards Selespeeds might be improved over the first versions.
Meanwhile, nobody's mentioned suspension arms, especially upper wishbones, anti-roll bar droplinks, anti-roll bar bushes... all are going to give squeaks and clonks but all can be replaced (provided you budget for it).
And of course, the infamous Variator rattles, either a rattling like hydraulic tappets for a few seconds after a hot start, or a continuous diesel-like rattling sound that disappears when the RPM is lifted.
Also listen for bearing noises from idlers and tensioners on the aux belt and cambelt. If anything sounds nasty, budget for a cambelt change soon and ESPECIALLY if it is due... interval is 36,000miles or five years... the job is worth 300-400 pounds...
In my experience, pre-2002 156s often have dashboard squeaks and rattles, plus squeaking from the heater fan and maybe from other electrical items (windows, wiper motor). Well you did ask what other noises to listen for
