All good advise already. Failing to learn about the engine from the sources mentioned you could do a little investigation yourself. On a new car to me I would like to know what the compression reading of each cylinder anyway. Look at your cylinder pressures to guess at compression range. Check valve train to tell if you are running a solid or hyd. cam design. Check your initial and total timing for a hint of what it shows or may be lazy to cover high compression. Then give it a listen and get a little aggressive with timing and drive it with a load (low RPM and in a higher gear) to induce pinging to see where you are at. If the purchase price does not cover the risk after all the facts you can find, pass it up till you find one. If you buy it then.........

Put a good tune-up in it and drive it like you stole it............... Enjoy!
