I want buy a Suv but? Is it difficult to maintain/repair etc.?

The last thing in the world I would get right now is an SUV or truck, since gas is projected to go up to $6.50 a gallon. I would rather go for a small car like a golf that runs on diesel that will get you more than 30 mpg. you'll be helping out your wallet and the environment. especially if you convert a diesel engine to run on used french fry oil. and it only cost about $100 or so to convert and most restaurants will gladly give you their used oil for free and all you have to do is filter the oil out and then put it straight into your gas tank
