I was thinking of buying a cheap (<2500?), low-consumption, small car, use it mainly for commuting and sell it after a while with probably little price drop. Is it viable? Or I will regret not leasing a new car?

Which cars do you suggest? What year/milage should I look at? I was thinking about <100k KM of milage. I don't need any fancy features (except low consumtpion); just flawlessly getting from A to B and not getting me into huge costs and a lot of wasted time.

Thanks
