I'm sure a decent Skoda is in that list somewhere 
I wanted a new Tiguan as next motor!
I was thinking about an Octavia, especially since it was rumoured that the VRS with DSG would be on the list, it isn't. Probably a good thing, with it's dated engine and high emissions the TAX man would bend me over. There are around 20 flavours available but none of them stand out as winner. Plus, the current body is getting rather old hat now don't you think? I will probably end up loathing it rather quickly.
Tiguan not on the list.

i would take the A3 but stay away from the toyota avensis as had oen as a company car for 4 years tried the new one and didnt like it just not for me but then again i did get offered a merc with a reduced tax rate haha 
Just had some bad news on the A3 choices after I questioned why many of the ones listed have higher CO2 and Power outputs compared to Audi's website figures.. It seems that many of them may be old stock. Waiting to find out what's what as it isn't clear.

Had the previous generation Avensis as a pool car for a while, it was OK but nothing I would want to commit to for four years.
Do you need a big family size car?
Your Mazda is family size, but if you don't need the space, go for the A3. If you need space you get a lot for your money with a Skoda Octavia
But I would say that.
I'd want an Audi personally.
I have found the Mazda's size very useful but not essential, it's size isn't why I chose it so it's replacement can be smaller.
Yep, A3 is the best of the lot. Golf is a bit dull I think, Bimmer looks fugly, Leon isn't as nice on the inside. Those would be top of my list, and worth a closer look I think. Wouldn't entertain even giving the French stuff a thought, Jap stuff just looks a bit cheap imo.
With you all the way I think but then at the moment it's not 100% clear which Golf its is, 6 or 7!?
I'm liking the look of the new DS5 tbh, if the diesel hybrid is on that list then it's got to be worth a look imo. 
Surely he wants a car to drive, not a reason to inspect the service area of Citroen dealer premises?
Parents got a 170TDI A3 run out on the previous generation.
It's a very nice appliance, as is everything on that list.
Can you avoid the 1.6TDIs and go to the 2.0TDIs - I know I would.
For a company car I'd be tempted by a 1-Series from that list, TBH, on the basis it's RWD and could be specced with standard skinny wheels and tyres instead of optioned to hell with huge, wide wheels. 
Jimble, I had a look at one and thought hmmm, they look OK but then as DH says, I'm not sure it's the kind of relationship I'm looking for. The first couple of cars I had from work were cast offs which always happened to be French. The most memorable being a fat ass Megane that was just plain awful to drive and riddled with problems, and a Citroen C4 which was almost as bad! These two cars amongst others have totally put me off long term use. (unless somebody can convince me that times have changed)
Thomas, funnily enough it was the fact that there was an A3 170 on the list that got me thinking that there's still some old stock on offer. Need more info on the others before I look any further. I can go for 2.0 TDI's but trim level is lower and no S-Tronic options. hmmmmmm. Plus CO2 is big deal for me this time round. Over the next four years it's going to be tougher on the comp car driver in this respect.
I do get drawn towards the BMW but something's telling me I'd regret it, just not sure what yet.
Aldi A1 in diesel format 
2 rollerskates in the family then 
Bingo!
AUDI A1 DIESEL SPORTBACK 2.0 TDI S Line 5dr

I don't need a massive car but this is just too small for my needs.
