not too up on roadsters, but I do know it should not be a handful to drive.
Who built this one, is it a well known shop, how does it run, is it squirrly or does it run straight.
Like any other type of car, look it over with a critical eye, your life could count on it. Do not make a desiccion right there, go back and look again in a few days or week. you will see things you missed the first time.
Does it need any updates, what is the chassis cert for, is it moly, mild.
Try to look at it with the body off the frame...
Does it need new suspension pieces.... all things to consider.
