I'm just buying a cheapish MGF VVC from Plymouth, intending to drive it back to London. The ride height is too low, and the suspension is rock hard. From what I've read, that seems to mean the nitrogen spheres need valves inserting and recharging, but pumping in some more hydragas fluid will at least raise the ride height.
First up, is it pretty much essential/highly recommended to get that done before driving a couple of hundred miles back to London? Is it even safe to drive as-is? How much should a pump-up cost?
Secondly, how would I tell for sure whether the cars been lowered (properly, not just releasing the pressure)? I understand there are modified knuckles available, but I don't know how they look different. Chances are slim it's been modified, right? Much more likely that a sub £1k car has problems than upgrades, I assume.
TIA for all your help - and thanks for all the information on here that's already come in handy when buying, knowing what sort of problems to look for. MGFs seem to have owner support networks like nothing else, that's one of the things that helped me decide to buy.
