The main advantage in buying used car is u got cheaper price for (if u r lucky) a still-good car. 1,2 or 3 yrs old cars with a good maintenance will be still in very good condition, moreover if the millage reading is still low and it pass a technical/ computer check. bring 1 of ur friend who knows about a car well. sometime u can find a very good car for a very good price, just be patient in looking for one.
