at that mileage and for how quirky expensive these cars can be I don't think that 2k is a bad idea. would need to be sure there aren't deductibles and what not, however a possible lifter issue, pulley issues, control arms ect can be costly and if anything this is peace of mind.
be sure to read fine print if you intend to mod so much as even an intake.
