Hello. I hope this is in the correct area. Im thinking of buying a 407 sw. I want Diesel and Manual. Im not sure what the best engine is to go for 1.6 or 2.0 hdi. We go camping a lot and tow a trailer at approx. 5-600kg and have bikes on the roof. So what do you people recommend and also if im going to look at some what is best to look out for? any common problems?
