I just got my 159 (from a 2.4 JTD 156) so can't speak about long term reliability (although there were some pointers given to me, which I list at the bottom). the general build and interior design quality on the 159 seems better than the 156 and streets ahead of its rivals (BMW/Audi) although the aesthetics are ofc personal (no they're not DAMMIT, they're just better!
The 2.4 JTD is a cracking engine but be prepared, you're not getting blueline super eco mileage with it. Look up the sticky thread at the top of the forum for this and you'll see what I mean. It's not that the mileage is bad, just not what we're led to expect from diesels these days. But then it has 210 BHP and sounds like no other diesel I've driven
from what I can tell, the watch points on the 159 are;
. Some colours (Red for one) seem to be a problem, see the sticky at the top of the forum. Mine's black and 2 1/2 years old having been parked outside the whole time and covered 35k km and seems good as new. My 156 was silver and same story, 8 years an no issues.
Nothchy gear change
. Gearbox is rumoured to be bullet proof and I've not seen any reports of GB failure since I moved from the 156 forum (where they litter the floor like so much confetti
) to this one. notchiness in the gear change seems to be a common feature, although it allegedly has no impact on GB life. Getting a mechanic to fiddle with the linkage and / or change the GB oil out apparantly can mitigate this. New oil didn't work for me, I'll get them to have a fiddle come first service. Frankly, though, I'm already used to it
on some Q4 models had some fault in the shape which meant they were tough to get full. Can be fixed, mine's OK
some apparently shipped with the wrong hydraulic oil in and this could cause power steering and even rack failures. Make sure it's been done (Hyd oil change)
I would have gone for a 2.4 rather than the V6 I got but there wasn't one available. I do love my V6 but I also do >30k km per year so the fuel costs are a constant reminder.
and as that lot said, if no kids (and no bikes, the reason I got a SW) then I'd go for a Brera, if only for the gorgeousness of it
