Hmm how does the handling of the 260 compare to the 190
like several here I have had both.

Try driving your 190 hard in the wet, under steer is probably quite noticeable. Drive a 260 in the same conditions and well it is a totally different and far more satisfying experience.

The most striking difference between the two will be the Torque, by comparison in 5th the 260 pulls from almost tickover whereas the 190 well not at lot happens really below 3000 rpm does it .

The 260 is not for everyone though it requires a degree of physical effort to move it about so t if you are a bit weak at the knees stick to the 190 everything is lighter and easier in comparison. The 260 has a real clutch and a gear change probably designed for ham fisted Red necks

Your main decision has to be can you afford the fuel.
I personally never got more than 25-27MPG from my ZTT so the 260 compares well unless I start using all the blowers abilities then it is rapidly sub 20s but I would never use my 260 for the daily commute anyway.
