Vectra C also worth a look... Wear mileage well and start from £250... Just avoid the dti and 2.2 petrol
Nice motors for the money
but many suffer dual mass flywheel ,clutch ,gearbox issues
worth looking into before buying
if it's been done, all is good, if there are any transmission noises ,clutch problems walk away (unless you are buying cheap and have factored in the parts/time
I've brought cars "spares or repairs" and fixed the issue before now,because that way you know why the car is being sold
(the astra G estate ,blown head gasket but 11 months MOT, £150 in parts and a couple of days working through it ,still going strong after 5 years )
a clutch on an omega could be done in a day ,£150 ? parts if you have lots of mot ledt and no other problems
aka better the devil you know
or plenty of omegas about with mot , buy one cheap with a long mot , say 500 quid lasts 12 months = £10 a week
