I have no experience with Mustangs. Honda is pretty good. I've got a Subaru with 235k on it that's still going strong. How many miles have you got on your leaf? I think they're pretty cool but they don't have the same capability a normal car.
Brakes are easy on pretty much any car but I'll do brakes, head gaskets, timing belts, pretty much anything. Most of that stuff is way more complicated on modern cars.
