I'm about to buy (tomorrow) a 77 280Z from a small local dealership. My question: is this a good idea to buy this car on a low budget? In other words will I always be fixing something on the car? I love these cars and have always wanted one, but money is a little tight right now. The car has 77,000 original miles on it and supposedly the motor has been rebuilt. Any help is appreciated!
