Delivery on a Freelander 2 built to order is currently about 3 months.
Mine wasn't tax free as i'm in UK but still got 13% of normal UK price.
Mine was a MY11 XS with sunroof, DAB radio, 6 CD autochanger, side protection strips and arm rests front and rear and full sized spare wheel.
Total price on the road was £27000 but that was UK tax paid.
If you look at the Military Sales Website and register they will send you a current tax free price list and advise on delivery times etc.
They're a bit of a bugger in some ways, whilst they'll give you an automatic 13% discount it's usually only on the lower spec models. I tried to buy a Range Rover Sport a while ago but could only get a discount on the SE and not the HSE. Well worth ringing them and having a dialogue mind, just do it you have nothing to lose!
