I currently have a lease car as a daily driver & priced it up by looking through "What Car" lease website (google it) I personally am now a convert if I were to be considering new.
Buying outright is OK if you KNOW you are getting the right thing for the right price, which I did for my Cooper S which will be the new track day car when finished.
Yes, you are forever paying, yes it is dead money etc. Have you ever heard of depreciation? Same thing, except you pay for that up front when buying outright. What I am getting at is there is potentially, no real world difference, so you need to cost up both options & see what is best for you and no-one else knows what that is.
