Not yet an Alfa owner, but seriously thinking about changing to a 159 2.4 diesel Lusso with tan interior.
Had enough of problems with hesitation in my Saab 9-3 1.9Tid 150 bhp engine (same as in Alfa's.........) and rather hopes that the 2.4 would be free from this. I suspect that the only way to be sure is to budget for EGR and possibly also DPF delete in the buying price.
I passed on a lovely one from Love Alfa in Birmingham 2 years ago and regret that - but it was the very first car I saw on that buying round and thought "There'll be dozens of others about" - WRONG again!!
Happy to hear from members with advice/info.
