I bought a Tao-Tao quad brand new for my daughter’s probably 6-7 years ago. I had to do some small things to it for the 4-5 years we owned it. Cleaned the carb a time or 2, a couple new solenoids, maybe new ECU, got all the parts dirt cheap on EBay. I had to repair the gas tank outlet, the plastic outlet tube cracked and started leaking. If you’re somewhat mechanically inclined it’s not terrible to own especially if you’re just going to be yard riding. I don’t think the quad would have held up to consistent trail bashing like 1 from the big 4 would. My girls did ride it on my track a bit and it withstood some single jumps, however. Not sure what you’re looking to spend but I picked up a KLX140 for $900 a few years back. Kawasaki ‘s KLX 110 and 140 are similar to TTR I believe.
