X300 was certainly better built than early S-Type's. There is only one way to run these cars: buy for sub-£1k and dispose of if/when it goes wrong.
The X300 driveline with the AJ16 and old 4-speed auto is actually quite long lived. Main enemy is rust, particularly on the chassis rails which kills them come MOT time.
You can also easily get a reasonable X308 XJ8 for £1-1.5k which have more modern electrics and engine. They rust as well and also watch out for failing gearboxes about 100k and O2 sensors packing up of which it needs 4 and they are expensive.
All like a drink and all are getting old but they are much more "Jaguar" to drive than the later S-Types and X-Types.
