Guys I have to agree with Irish Medic..
I did a lot of research before buying my P38, and decided the TD6 with its 2.9 Diesel was the best one for me, but when I actually sat in one, it just didnt feel right, and was not comfortable for me at all, so I scrapped the idea alltogether, and decided to buy an X5 instead. Then I checked out a P38 2.5 for sale locally, sat in it, found it was so comfortable, I could live in it, took it for a test drive, found it had enough power for me, and took the plunge..
How it will span out, I dont know, only time will tell, but to me, comfort is of more importance than 0 to 60 speed.
Just my 2p worth..
