The 3Racing Sakura Zero S is a great sedan but it has been replaced by the newer XI Sport. You can still buy the Zero S and Hobbyking now sells them as re-badged the TD10 selling for less than $66. Amazing deal and the kit includes tires, inserts and rims.
The car works fine right out of the box, but to make life easier for the driver it needs a few upgrades. A better out of the box economy sedan is the Spec-R S2 which has just been released and sells for under $110. This needs doesn't need any upgrades or mods and is probably the best value in a 4wd sedan today.
