In 1987 I bought my first “real” bass, a Yamaha BB1100s, was £400. Fender Precisions were about £325 (and out of stock hence the Yammy purchase).
Now at that time a pint of beer was about 70p so a Precision was equal to approximately 460 pints.
Nowadays a pint is around a fiver and a Precision is about £1700, so approximately 340 pints.
