Mondeo TDCi or Insignia CDTi ??

Help wanted please.

I currently tow our 2009 Bailey Pageant (MTPLM 1435kg) with a '56 plate Mondeo TDCi (130bhp) and it does it brilliantly. I never buy cars new, usually at a year or two old.

Any comments/advice, pros/cons on the two cars would be appreciated. The Mondeo would probably be the 140 bhp version, the Insignia the 160 bhp. Not too worried about the internal trim etc - it's how it performs with a van on the back!

I love my Mondeo and would stick with it but there are amazing bargains to be had on the Insignia... Over to you please.
