2014CDTi

Hi guys, I am looking to buy an Insignia 2.0 diesel CDTi ecoFLEX SRI today. It's a 64 plate. £3,500 with regular oil changes and 94,000 miles I am just wondering if you guys can help me with what I should look for when buying this car. Does this model have the oil pickup seal issue? Should I be looking to see if the timing belt has been changed? Do they get the issues with the subframe? If there's anything else you can advise on that would be appreciated. Thanks!
