Not enough to buy the new one. I still buy the 08 versions when I find them. Never have problems now that I use good o-rings & never had the problems that the updated cars supposedly fixed. A plus with the old car is my pinion bearings fit for wheel bearings.
Teeforb I'm one of the 2 guys @ ARC thats been running the 808 since it came out. Have you ever seen my car break?
