My first Civic was a lease car, 6 months old with 14K on the clock, saved about 5K over new price, I went on to do 180K in it and never a spanner on it.
No point in buying new, depreciation in first 12 months is quite bad, savings on buying nearly new can be massive, as far as I know second hand cars only attract VAT on the difference between the price the dealer buys them at and what he sells them for.
