Oldroverboy in rainy west wales here. got an epica diesel and an aveo lt, sold my lacetti sw last year after building a house and using it for everything. went when started to run badly (stuttering at about 30-40mph)and couldn't cure. PS...garage couldn't cure either! Other fault was central locking had a mind of its own when it rained....
but excellent fuel economy, and very qick and reasonably sure footed on motorways and a roads. car always serviced properly, not egr valve or fuel filter, not air filter or airflow, catalyst ok no faults shown on ecu, all this started within 1 month of expiry of warranty. but no complaints, cost peanuts and got good price as trade in.
cost of ownership was about £100 a week so not too unhappy especially after the work it did.
