...buy 30 years old Corolla(KE70)?

Its a sedan with a mighty 1.3 4K engine, closing in to 400k kms. Seems okay, some rust on the wheel arches. It was well kept, always in the garage
Its cheap, really cheap.
A chance to swapsome 4AG-E goodness in it and profit?


(Oh and. Girlfriend is threating to kill me if i actually buy it. She's small but im sure she is capable of plotting a murder)
