Hi Scotty, love the videos, keep up the good work! My wife an I just purchased a used 2009 Toyota RAV4 Sport (V6 4WD model) with 70k original miles and it's awesome, we love the thing. The catch: this was an overseas military family vehicle. US Air Force family stationed in Germany drove it for 7 years before bringing it back to Oregon (yes the vehicle is US spec, made in Japan - imported to Germany from a special US military dealer). With the RAV being driven all over Germany and the rest of Europe it's covered in rust underneath the car and in the engine bay due to lots of road salt and Autobahn use/abuse. I took it to a local Toyota dealer for a pre-purchase inspection and they said the rust isn't that big of deal - I will likely have to replace the muffler/exhaust in 3-5 years but other than that the rust is purely cosmetic. All body panels with paint are rust free but the underside and engine bay are covered in rust.
My question to you is this: Is surface (non-structural) rust something I should worry about on the underside or engine bay of the car? Is there anything I can and should be doing to remedy the rust issues? Should I clean off the driveshaft, transfer case, transmission, oil pan, coils, etc.. and paint them to protect them? The local Toyota dealer said they see rust like this sometimes but usually only on cars 2-3x the age. When asked if they could "fix the rust issue" they said they will NOT sand down and paint over any rust to protect it, that's for a body shop they said.
Cheers and thank you in advance,
