Smaller wheels with a larger profile would make life more comfortable, but not sure how much better it would be than it is currently? I would only switch to diesel again if I was doing the miles to warrant it. Most of my driving is in and around Nottingham with the occasional (okay quite a bit lately) jaunt across the country! Diesels suffer a lot driving in urban situations and the MPG is shite unless you're on a long run! Diesel Accords also have a list of problems which can be expensive to fix too! Clutch, Flywheel, Injectors, Inlets can all fail! Then you've got EGR valves that'll clog up because of short journeys! If you do go for an Accord, get the 2.4 petrol at the very least!
