I would keep it, if you can afford to do so.
I got a quote through Admiral multi car and it was fantastic for my VRS and a z4 3.0 - something like £800 for the year with a combined mileage of c.14k split 50/50. Gave me full no claims on both cars.
In the end I decided I didn't want the hassle of keeping two cars as I can use the Alpina as a day to day as I have a nice country route to work, but next time I will keep it and get a family wagon.
