AFAIK, the 525i is already fuel-injected while the 260E is still carbureted.

The early 90s E-Class is among the best Mercedes has ever made. In 1994, they are #1 in the JDPower tests, but a few years ago, they're already among the bottom. This car you plan to buy was very thoughtfully made. It has a silky ride and very much a classic inside and out.

The 5-Series is a different car altogether. Rather than comfort, it's made for performance, handling and fun. I also find it nice-looking. It also seems fewer here compared to its Benz counterpart.

So what should you choose? If you're the driver, you are to lean towards the Bimmer, but if you have someone to drive for you, you'd be better off in the Benz.
