Would you regret a car engine downgrade?

I have a ford fiesta zetec 1.4l 2005 and want to buy a new corsa limited edition 1.2l 2014. If you go from a 1.4 to a 1.2, would it annoy me not being able to accelerate as quick? Would i notice it?
Also, my friends new corsa 1.2l engine has a better sound than my car, why is this? Just coz its newer?

Is it possible to fix an electric wing mirror easily?

I have a ford fiesta 2007 with electronic wing mirrors. Managed to take the passenger side mirror off but only the plastic, literally no damage to the electronics but can't seem to find just the plastic casing parts so it seems that my only option is to replace the whole mirror. How easy is this to do? I don't want to damage my car more but I also don't want to pay if it's a job that could be done by me (though I'm a novice).

Any advice appreciated as it's due for MOT soon!

Headlights not working on ford fiesta 58 reg?

Both headlights have stopped working simultaneously on main beam. They both work on full beam. Is this likely to be a fuse? I here there are separate fuses for each headlight so I was wondering is this a common fault or could it be numerous possibilities? I.e both bulbs gone simultaneously, is that likely? The weather has been good so I assume that no water has got in.
