Really hard to say as it's mostly personal preference. Diesel cars are becoming more popular by the day. But it takes a Certified diesel mechanic to work on them. Also the cost of diesel fuel as compared to gasoline . Lot's of factors to weigh in. After working on cars almost 35 years, it would really matter not to me. Get the vehicle that best suits your needs.
Besides what Rooster said ... If I were looking for a vehicle these days, I would look for a diesel. Why? Because if you believe we will soon be looking for alternative fuels, a diesel can run on "biodiesel". There are even people who set up their own "plants" where they convert restaurant waste (cooking oil) to biodiesel fuel.
