ive been speaking to somebody at work who’s next door neigbour has brought an s2 exige and he leaves it on the drive with no cover or anything and last couple of days its been raining he told me car was fine, although he has brought a small waterproof cover that would fit over a normal size chair and puts it over the engine and then closes engine bay and says works wonders. just lift cover out and give it a shake. one step closer to getting exige!
