Yes, buying a used 1/12th car can save lots of money, but here are a few things to also look/look out for....
-buy from a reputable racer/seller one that will tell you what should/could possibly need replaced soon
-stay away from cars that have a cracked chassis, or axle
-stay away from graphite or aluminum axles, they aren't as durable as fibreglass
-with the exception of bearings rebuilding diffs is cheap.
-try to get something with foams, even if they aren't the right compound as long as they will run for a while they are mounds better than none. this goes for a new or used kit.
-pay a little extra for a car that includes a servo.... they aren't always the cheapest....
-try to find someone at your track selling one, you can call upon them for advice/information, and you get to see it first hand before any money changes hand
-The old skool front end is alot cheaper when you need to replace parts and easier to get set-up correctly
