The Honda V6 is a delightful engine, lots of power, smooth torque delivery and a truly wonderful 6-speed gearshift (manual). By contrast, the Golf had longer throws and a less-intuitive clutch pickup. And a LOT less power.
The Honda felt like a much bigger car. The rear seat (despite being a coupe) had plenty of legroom, but a bit short on headroom. The trunk was also magnificent. By contrast, the VW has great space efficiency but no getting around it is a small car.
Our past Hondas have been the most reliable cars we've owned. I would expect the Accord Coupe to be much more reliable long-term than the Volkswagen.
The Honda Accord coupe is very attractive and has more of a timeless elegance in style. The VW shape is ubiquitous and boring.
