Having had a redundant car for almost a year, when I drove it a few weeks ago, water was sloshing around inside. I took it to the garage as the exhaust had snapped on the same journey. Mechanic said he took 4 litres of water from the car but my back seats, rear passenger footwell and front passenger footwell were soaked. I collected it yesterday with a new exhaust and a Dried out rear seat. Happy! Rain overnight and where the back seats would be there is water (literally a thimble size) on the left side and the Footwell are soaked again! I just don’t know what to do. The mechanic said he sealed the boot seals and tightened the boot yet water is still getting in! I’m pulling my hair out. Please any advice?
