some connects ive viewed were like tractors, slow and sluggish. getting the right one , right price+
That will probably have been the 75bhp tddi. You want a tdci. I have the 90ps version, it does me fine, but if you can get a 110ps go for it. As well as being faster, they are apparently more economical too.
I have had my 2006 230tdci for nearly 4 years now, had just under 60k miles when i got it, now at just over 101k. So far, touchwood, other than a clutch (and i am pretty sure i know why that went, and it was my fault!), it has not needed anything other than routine servicing.
