Ello there just brough a 98 vectra for just 7500 but theres a couple of little niggy things wrong with it 1., when depressing the accelerator i can hear a pop and a hiss 2., when braking the brake warning light comes on but there working fine? 3., the ecu light comes on quite a bit and the lights will flicker and the car will feel really juddery then it will be fine 4., the gears sound like there a bit clunky sometimes, I have been able to set off in 2nd a few times. 5., theres some black smoke coming out of the exhaust sometimes but im using normal petrol I know theses are only minor problems and i think i got a good deal on the car so im prepared to pay a little more to fix it up. Thanks
