Sat too long. Will need paint, bodywork, tires, brakes, glass replacement, new ignition system parts, carb rebuild, gas tank attention & a fuel pump, water pump, possibly an exhaust system, some radiator work and of course a clutch. It could some interior work too. Now you've spent about 4 times what the car's actually worth. If vehicles like this are your thing, it's better to buy one that's already done or nearly so.
