Since I don't own an ES, I can't really compare maintenance costs, but I can tell you that if you need dealer-only work, the Toyota dealerships around here are clueless when it comes to "Soarer," but obviously well versed in "Camry." Just from a production number standpoint, I'd say that the ES is going to be cheaper, but I wouldn't say that the SC is a maintenance hog, but it isn't a Camry, either. IMHO, it's an "Apples to Oranges" comparison anyway. One is a high-performance luxury coupe, while the other is pretty much a warmed up FWD grocery-getter. Personally, I wouldn't buy a salvage title car, especially not a Lexus. Maintenance and TLC from a previous owner's standpoint means too much for me, since any major problem + fixing the known issues could cost you the difference between a salvage title SC and a legit car with service history. From looking at a fair number of salvage title cars, I can tell you that most were never fixed properly enough to be safe, not to mention the inevitable issues such as water leaks, messed up wiring, and poor fitting body panels. I'm guessing that those bags are going to cost you $1500-2k alone.
