Run it through Carfax, see if it’s had any major work.
uhhh is carfax international?
If it’s not, can you get a local police agency to check if it’s been in any accidents etc. it’s not perfect but may work.
Ohh, not sure, but there may be a similar local service, carfax is a standard for decades in the us. Oil leaks are another bad sign, stains on the cement under..
is there a good site to research different models?
