I have a 2004 Acura MDX that I inherited from someone else last May, and since then I've come to realize just how terrible the gas mileage is. I drive around 200 miles a week, and considering the price of gas, the fact that this car requires premium gas and that it gets 14 MPG, I pay around $175 for gas every month. However, this car has had to have a ton of repairs and maintenance done in the past 8 months, so much so that the dealer I take it to knows the entire car inside and out, so I know the history of it and my dealer is familiar with it. With a used car, I still don't know the full history of it and what could potentially go wrong. Would it be a good idea to trade it in and get a smaller, more fuel efficient car to cut what I have to pay a month in half or more, or because this car has already had so much done to it, over $2000 in maintenance, would it not be worth it to get another car after I've put so much extra money into this one?
