I wouldn't drive all the way there as I get very tired on long journeys these days, and, anyway, my wife hates travelling by car. Given that the she moans and complains about my driving all the time and has hysterics if go over 70mph, the tiredness may well be explained by the circumstances.
But that apart, I'm not sure you'd want to be driving an Omega round Naples - I know how manoeuvrable they are for a big car, but Naples is BUSY. On-street parking is impossible, off-street is in weirdly-shaped basements and you won't fit an Omega into the titchy little spaces.
On the other hand, Naples airport carhire is a total shambles, and getting out of there is difficult - the airport seems to be in the city. The Italians seem to favour small underpowered cars, the sort where you have to turn the airco off to overtake. And once you get outside the city, autostradas excepted, the roads are narrow and very crowded - not ideal Omega territory, especially if you are concerned about your paintwork. But trying to coax a 1.2 litre Fiat Punto hire car up a mountain road in 35o heat with 100% humidity is not much fun either. You really need to get a more powerful motor, but the hire costs rise dramatically if you do.
The car we hired had something wrong with the steering - never worked out what - but it just didn't go where I pointed it, with the result that I managed to scrape three cars just getting out of the city, before I worked out it wasn't my driving that was the problem. Fortunately, no-one cared, and I'd paid for the no-excess option - highly advisable there.
Italy is wonderful - I love it. But the driving is a nightmare.
