remap gttdi. Just look at rhysos torque!

And a chipped gttdi will probably be far cheaper on insurance than a v6 4mo anyway, even if the gttdi had an R32 bodykit.
Id stick with a gttdi purely because of cost. v6 4mo is £400/year to tax, and it drinks petrol at a nice fast rate, yet a gttdi will be economical (more economical after a remap infact if driven sensibly) and tax will be cheaper.
