Not so much that the Camry isn't user-serviceable, my problem is that I'm used to my Suzuki where every single part comes out and I can replace individual pieces of each part or clean the individual pieces of each part- The way the MAF on the Camry is designed, as an example, means that once it starts causing a ton of intake noise it's gotta go. None of the individual parts of the housing can be replaced or fixed by the owner. Gotta buy a whole new MAF housing. No big deal, I'm just used to not actually having to buy stuff to fix other stuff. The Camry is just fancier than my old Suzuki, is all!
