Does the Almera have Renault mechanicals? I know Nissan and Renault share a fair bit these days (like the diesel engines) - Nissan don't use Renault autoboxes do they?
------------------------ The newer Diesel Almeras use Renault engines. Other than that, I don't think so. The Almera has a Borg-Warner autobox in it (I think). Quite different from the Renault one, because the latter is sealed and has neither dipstick nor place to top it up, whereas the Nissan has both. I heard from the gearbox guy who fixed our Renault that Renault have switched to using Nissan's auto boxes in their newer cars, so maybe the problems with Renault automatics are a thing of the past
Did you mainly use the 307 from cold? If so, it would sound like a tractor. And was the Polo just a 1.9D or a TDI? If you ask too much of any turbocharged anything at too low revs then it won't respond that well. But yes, there are better and not so good diesels out there.
------------------------------- No - I drove it some distance, and this was in Nice, so it wasn't ever really cold. The thing that shocked me was how terrible the gear change was (and before someone says I don't know how to use a clutch, I should point out the autos are driven mainly by my other half, my day to day car is manual); the clutch felt like it wasn't disengaging fully, and this on a car which had about 6km on the clock when I picked it up. It's manic enough driving in that area without having a car that keeps getting stuck in neutral. I also didn't like the daft double-opening rear door/window thingy, or the control layout. Don't know what the Polo was offhand, but I doubt it had a turbo; didn't feel like it, anyway. Actually, come to think of it I've driven a big Volvo estate which was a Diesel, and that was OK, and BMW diesels I've been in also sound OK.
