My new roof has arrived and is now fitted to the car. Doesn't seem to have made much difference to the leaks, water is still pissing in . I think some new seals and possibly cant rail rubbers my be in order. Anyway, whilst I have a spare roof I may aswell send my original roof back to Lotus for a refurb and sell the spare once its back. I'll probably end up keeping the original roof since its a bit easier to fit than the replacement - its probably been stretched over time.
Lotus have quoted Â£41.14 for the refurb but Im still waiting to find out if I have to go through the dealer, fingers crossed I will be able to post it directly to Hethel and avoid having to deal with Stratstone.
On another note, my touch up paint a wheel nuts have arrived from eliseparts, just need to wait for a dry day before fitting them.
