Replace every failure prone component you can think of-for example, the MGM in my sig got 2 front Timken wheel bearing assemblies when I bought it (right at the end of USA manufacturing of them), new coated rotors & pads, new TYC radiator fan assy., new A/C accumulator(rust), new tires. PO had already done the transmission flush, had maintenance records (but did several short OCIs with synthetic regardless). Other than collapsing chain tensioners & a little PS noise when sitting & really cold, it can (& has) gone anywhere.
