What should I look for in a used Vauxhall Monaro coupe?
The Monaro's engines are understressed, even in the most powerful VXR models, so they're unlikely to give trouble. And, the car has been around in Australia for many years with no reports of mechanical problems.
The main things to watch for are signs of abuse and crash damage. Make sure the car sits straight and true, the tyres are evenly worn and there are no scratches or dents on the underside from where the car may have gone off the circuit on a track day. The rear tyres are pricey to replace, so check their tread depth.
Apart from that, there's little to worry about with a Monaro other than carrying out the usual history checks and insisting on a full service history, which most cars will have. Also make sure the car is an official UK import.
