Best engine for X351

what year did the Aluminum body come out?

and which engine has proven the best for everyday reliability ,V6, V6 super, or V8 supercharged??

hello, anybody home??? been a month.

The X350 was the first to have the aluminium body in 2003 I think.

My X351 is a 2010 Supersport and all I can say about reliability is that after 55000 miles everything is still OK.

I have a 2012 X 351 5.0 V-8 68000. runs like a top…However cooling system failed…water pump and all the pipe

Our 2012 XK convertible 5 litre needed a new water pump at 50 000 miles . Jag dealer replaced free of charge , even though just out of warranty . Answer was you are a loyal customer here .
Thank you , great dealership .
