Assuming this has the Vulcan 3.0 OHV V6 . . .
I suspect you’ll be doing the fuel pump and the oil pan gasket sometime in the next few years of ownership
Another thing, which I’ve seen frequently, on your future car . . . the AC compressor tends to seize, which starts a chain reaction. This throws the belt . . . I know the belt is supposed to freewheel with a seized AC compressor, but that’s not the way it works out on this car. Then you have no power steering, no charging, no water pump, etc.
If that happens, you need a new AC compressor, belt, accumulator and orifice tube
This does not happen due to lack of maintenance, in my opinion. It just happens
If there’s a chirping noise, it could very well be the cam synchronizer
The front sway bar links are very likely to be worn out. The boots are probably torn by now
Make sure the brake booster shell isn’t wet with brake fluid, or have blistered paint. that would indicate a leaking brake master. Seems to be common on this car, after several years. Not a big deal to fix, though
As soon as you buy, unless you receive a stack of maintenance invoices, you should treat the car as if it’s never received any maintenance
