Is this worth the swap?

Only person who can answer this is you. We don't know how much money you'll have to stump up for the diesel, nor how long you plan to keep the car. But it is simple enough to work out if you have real world mpg figures for the diesel.

Is there any downfall to owning a diesel currently?

Doing that kind of mileage, no.

I’d keep what you have and spend a couple of grand on a cheap commuter to soak up the miles running to and from work. It would pay for itself via greater economy and in the reduction in depreciation on the big VW. Any expensive car you put through an 160 mile daily commute is going to plummet in value.

I just bought a Skoda 190 petrol and get similar mpg up to 50 on a run. Check the price difference over VW. I wanted a 280 but couldn't find one...Happy with it though surprisingly as I was after a premium convertible
