hi all , a friend of mine is in the market for a smallish coachbuilt or possibly a-class and has asked me if i could get an opinion on the 1.9 diesel engine. he's seen a few vans that he likes with this engine but he's not sure about it and wonders if he would be better off with the 2.8 jtd lump ? thanks in advance and any info will be gratefully received and passed on , safe travels sean
