A 3/4 does look good, but imo, not worth the hassle or risk.
Risk is a personal think chris but i've had a 3/4 plate for the 6 years and 66k i've had the car, been on many of the same roads as you and never been tugged for it.
Fair point. I think my main issue is that I've not really had much of an issue with either the VX or the Elise full size plate. In fact I went through more front plates with my old Mini - which is not only low, but the bit that holds it on basically makes the middle a prime suspect for snapping it in half when anything hits it!
I actually ended up with an alloy plate behind it to stop large stones smashing it to bits!
All that said, we have pulled the front plate off the VX 3 or 4 times (including small clam damage first time around)
