What should I look for in a used Volvo C70 coupe?
The C70 shouldn't let you down as long as it's been properly maintained. So have a look at the service history to make sure no intervals have been missed. The turbos are reliable but have to work hard, and if an oil change has been skipped it could spell trouble.
Check the wheels and tyres, too. The bigger the turbo, the bigger the car's hunger for rubber, so see how much life is left on them. Worse still, if the wear is uneven or irregular there could be problems with the front suspension or driveshafts.
If the front footwells are damp (feel the carpets) you might have the C70's trademark door mirror leak. It doesn't affect every car, but is notoriously difficult to fix.
Finally, there were a couple of recalls on the C70, both of which concern the airbags and Side Impact Protection System. So, check that any necessary work has been done. Any Volvo dealer will be able to look up your car's recall work.
