Do you do all your own work? If so, you will not be happy with a newer Volvo. Many of the repairs require getting fault code information from the computer via a machine that costs $50,000 and only dealers have. That means that owners and independent mechanics are limited in what they can do, just because Volvo is withholding the information. All modern cars have computers, but not all manufacturers make it difficult to get the fault codes out of the computers.

Much of your decision will come down to whether you just want to change cars. It is not going to cost you $15,000 to keep your 740 going, but if you want to have a newer car, that's also part of the equation.
