C coupe sport advice

[pants fm]

Hi folks. Just joined and looking for your thoughts.
Driving a Mazda 6 TS 54plate but have my eye on a C-class coupe Sport.

Looking to spend upto 14500.

Want leather but not sure if black or black/white looks better.
Manual or Auto (never had an auto or a even a merc for that matter)
Petrol or Diesel
Fancy black in colour

180K, 200K or 220CDI appear to be popular enough. Don't want the bigger engines.

I'm in Glasgow and have 4 weeks off work so hopefully get something soon.

Cheers

Thanks for the replies. Always better hearing from owners than reading magazine reviews.
Just need to find the courage to tackle the car dealers ha ha.
Let battle commence.
