In reply to Jimbo W:
Pretty much anywhere outside the car that could get wet and accumulate water should have a drain, they gradually get blocked with slime and muck. I'd look to see if your accumulating water problem is blocked drains. The plastic at the base of the windscreen is usually just a tidy-up piece and splash cover.
Do you mean the oil sump? A fix if it's a hole or worn out (droopy suspension?) will require removal, clean-up, welding and re-fitting. If it's steel it's easy, if it's alloy its still easy enough but it'll need a specialist welder and the chance of success is lower (pinholes, cracks developing, warping... I've bitter experience here!). Easier might be a breakers yard sump. Clean it up, bolt it on with a new gasket. Cheap, easy, messy enough it's not a job I'd relish.
Droopy suspension is probably tired springs. The fronts will require the removal and stripping of the struts which requires a spring compressor and very likely a balljoint splitter. The rears on most hatches can be wrestled out by undoing the top or bottom nut on the damper, lowering the suspension arm to its stop then getting stuck in with a big pry bar. How easy it is varies from car to car, some are easy. I failed on the last one I tried mostly through not having a ramp (making it awkward) and not having a big enough pry-bar.
Put fuses back where the wire links are, a car fire could spoil more than just your car
