What year CLS to buy?

[Looking4aCar]

Hi guys

I am looking to get my first Mercedes and have my eyes set on the CLS. Dream would be CLS63 but my budget right now is £20K - £25K hence am looking at a CLS 250/350 AMG Sport.

I have a couple of questions I was hoping you guys could help with:

• From 2011 - 2014 are there any significant changes to the car that would mean getting one year over the other would be better?
• 250 vs 350 whats the general consensus here?
• Given the Mrs will also be driving it will have to be an automatic

Thanks guys.
