[modern] 1995 XJ12?

I have an “opportunity” to purchase a 1995 XJ12 with 22K miles on her for
around $34K. I’m concerned about the V12 engine (fuel economy,
etc…) however. I’d love to hear from other Jag lovers who can help me
with my decision to purchase or not. I originally wanted an XJR but having a
hard time locating one. Is this a good deal or should I wait for an XJR??
