RE: Mini MGT vs MT Spec 3.0
That CEN is a 4wd stadium truck platform, with a 2 speed, and bigger tires. The MGT 3.0 is an actual 10th scale MT, not based off a stadium truck at all. Look closer at the chassis, and design of the trucks. You'll see what i mean. Sounds like you like your brother in laws CEN though. So if you're wondering what to buy, then just get the CEN. You can share spares that way too.
