Tbh i wouldnt be too worried. most of these kind of thefts where they break in the house n take the keys (im assuming thats whats happened) theyre after new or newish cars, i doubt theyd be interested in an old starlet if they even knew what it is. Unless you have other new cars on the drive, then it might be different as they might just grab whatever keys they find
even if they managed to get the keys the car aint going to move without the fuses...rather be safe than sorry!
