Classic insurance is the way to go if you do less than 5000 miles per year.
I have a multi car policy for 5 cars, 3 of which are off the road. The 2 I use on a daily basis are a standard Scirocco Scala and a much modified Corrado. The latter has an R32 motor, giving over 250bhp, Quaife diff., lowered, 17" alloys, uprated brakes. Costs me about £450. The advantage of having 2 cars on the go is you can do more miles and if you have a problem with one, you still have a car to drive! I don't have a more modern car.
