I'm on a 10-week contract, and because I'm 23, it costs about $150 to rent a car every weekend, which works out to about $1,500. However, becuase I'm only here for 10 weeks, is the hassle of buying a car, then reselling, worth it? There are some cars going on Gumtree and there's a second hand car market on this weekend which I'll go to anyway because I have no plans this weekend, but just cautious of buying some $1,000 lemon. If I do buy, what are the things I should be looking for? Thanks.
