How many people still have the undertray on there classics and does it make any difference?

Reason being the previous owner of my car snapped the bolts off so it is held on with loose fitting cable ties and a few people said i may as well not bother but i was wandering if it makes any ifference with it on or off and if it was worth paying for the garage to drill out and rethread so it can be bolted back on properly?

Do you mean the metal heat shield or the plastic under guard?

I have the under guard and I searched alot of places to find one. I like the fact it gives the sump and exhaust manifolds a bit more protection, especially as I have a static dropped classic.

If you are referring to the heat shield, I would also recommend you keep that, mine came loose and gave an annoying rattle, but out of some jubilee clips I managed to re-secure it.

Anything that has been held on with bolts and sheared, go out and buy some easy outs from screw fix and some taps. It's an easy little job.

Yes its the Plastic under guard. But does it really make any diffrence?

I'd say it probably improves aerodynamics, trying to flatten the car floor, as well as perhaps helping to pull air down from the tmic scoop. But of more concern is the protection - it will help stop water splashing up and wetting hot exhaust (sudden cooling could make them crack) and given how low down the spark plugs are probably helps keep them dry too. I've had to drive through some very deep water on occasions and can't imagine it would be possible with the spark plug leads covered in water.

Fair enough i'll get the garage to drill them out and put new in when it has some work done since unfortunitly they are broken of a few mm into the frame and rusted in so not easy job to do myself.
