you can do a P38(your current Range) to a L322(what you want it to look like) conversion. Go to
www.rangeover.co.uk there you can see finished pics, and your current Range can look exactly like the newer model Range, you could probly even pull of the new headlights, but it wont be cheap and I don't think it would go on very easily, but it might, I just dont know. But RangeOver.co.uk has some great pics and compare side by side the P38 and L322 and it is hard to tell the two apart
