I tried the p450 jaguar and love it , but before buying it I wanted to know the difference between the p450 and the old version of the ftype (550 hp), on the below point :
sourds of exhaust when the option is activated
fiability EDIT : readability
If there is new option available on the new model that I must buy.

Thank you guys

 

What's fiability?

Sorry, that was the French version of reliability lol
I corrected

 

No problem and I learned something today!
It helps if you put where your at as it's hard to tell if it's a language problem or someone posting from a phone with some weird kind of spell check.
