I'm afraid not - the 50% first year allowance disappeared a few years ago, and even then was not adjusted for short periods. Capital allowances for cars are now based on the CO2 emissions.

Potentially. It depends on what the running costs are likely to be in terms of actual fuel costs, insurance and repair bills. You will have to do the maths to work out which is the better route. You would have to keep some kind of mileage record either way, in order to justify your 80:20 split.

You could choose a year end of 30 September 2011, however your first basis period would still be from 1 October 2010 to 5 April 2011, so you would still need to submit a 2010/11 return.
I would advise you speak with an accountant about some of these issues - the last one particularly, as there may be tax advantages in picking a certain year end over another.
Hope this is of some help.
