Ferrari California purchase

[Briza]

So, finally thinking of getting a California, I know they not everyones cup of tea, but I love them, haven't fully settled on colour yet, they look great in black with cream interior, but also like them in red, especially with a black roof.
Anyway, I will have to finance the car, as it happens, our fixed term mortgage runs out next month, we have a lot of equity in the house, so was thinking of taking out an extra 80k to buy the car, interest rate is 1.59% and would do it over 10 years, I figure if i get tired of the car could sell it and pay the money back off the mortgage.
Feel free to point out the holes in my man maths!

Thanks for the replies chaps, you've got me thinking about falling prices now, do you think the California T will fall below 100K by this time next year? I know its crystal ball stuff, Im still kicking myself for not buying a 355 years ago for 35K, a lovely yellow one i took for a test drive, a private sale, i ended up buying a TVR T350t instead, ah well.
So, should i leave it a while in the hopes of a better car for the money?
