I Agree with Dilesh. My Parents have had diesel cars as long as I can remember. Also I've been using diesels cars for the last 2-3 years. The maintenance is not a nightmare as people would like to think.
Diesel cars are taking the world by storm these days with every manufacturer adding more diesel powered family rides and even sports cars to their list. However with the restrictive car taxes we will not be able to enjoy the latest technology diesels have to offer. But for day to day running, a diesel car will be lighter on your pocket, even after you pay for a complete engine overhaul.
