New car talk (finance) - worth it?

[ginge191]

So i'm in a bit of a pickle over varying opinions and such so i'll chuck this out to the enthusiasts community and see what you guys say

I'm in a position to purchase a new car, brand spankers, 'rare' car, as in, only "100 for the UK market" rare.

Now speaking to my local dealership who have bent over backwards to source me the car and i've come up trumps; there are 2 left...

Now , my only issues is the finance; due to the nature of the car and probably the dealership as well, they don't offer a 0%; instead it's a 11-14% variable.

The monthly payments i'm looking at wouldn't put me out of pocket to the point i'm broke and would also mean i can still put into my mortgage pot.

I can put anywhere between a 0-40% deposit down; but realistically i'm looking at paying finance over 5 years; which they're happy with, as am I.... well... i am before speaking to you rowdy lot.

So, can anyone experienced speak wisely as to finance and options?

Please keep this sensible and on topic
