Best way to purchase an M3

[berb_uk]

I'm seriously considering placing an order and would like your thoughts about the following ways of paying for my M3 (rough price=£60k):

1. Cash up front. (no interest to pay but then money somewhat locked up in the car)
2. PCP (i.e. balloon payment at end of 36 months; higher APR I suppose?)
3. Hire Purchase (lower APR)

Would appreciate any help as it will be the first time I am purchasing a brand new car from a dealer. Very happy that it will be a car as good as the new M3!
