The petrol V8 v Diesel TD5 decision involves the heart as much as the head. If you like quiet swift pull away from rest and 5 km per litre economy then go the v8. If you can put up with sluggish pull away and noisy idle but love the range that 10 km per litre gives you, then go the TD5. I have had both and would choose the TD5 (I am over 50 now!).
The auto v manual is easy. I have had both - automatic is much easier around town, much better control when rock crawling, much the same in sand and no clutch to replace, ever.
