I'm no expert on Espaces but I'd go with the 3.0 but that's just my personal preference. Someone keeps telling me that there's no replacement for displacement
Points to consider though;
A 3.0 dci Auto will get you to 60mph 3 seconds quicker than a 2.2 dci Auto and 1 second quicker than a 2.2 dci Manual.
A 3.0 dci will get you going 10mph faster than both a manual or auto 2.2 dci
A 3.0 dci is an insurance group higher than a 2.2 dci so factor in a little bit more for insurance as well as fuel bills.
Lastly and I'd say the biggy. CO2 emissions for each varient are as follows;
- 2.2 dci Manual 206g/km
- 2.2dci Auto 246g/km
- 3.0dci Auto 252g/km
Now, either from 2010 or 2011 (depending on when the new car was registered) you're gonna be paying £425pa on road tax for both the 2.2 and 3.0 auto's whereas the 2.2 Manual will only cost you £245!!!!!
There's a few points for you to consider. Now, me, I'd still go for the 3.0 but I don't know your wallet so factor the future costs
