Should I buy a VTL Siegfried mk1 basically new 700 hrs?

I’ve an opportunity to buy a a mint hardly used 700 hrs original tubes VTL Siegfried Mk1 with updated regulator boards. They’re being sold locally through a dealer who originally sold them to this client. The owner never used them that much over the 20 years he has owned them, only 700 max and they’re spotless condition. He’s firm at $17,000.
some of my concerns are the capacitors age and overall reliability of the Mk1 version.
Other concerns overall heat and VTL support, which has be known to be less than enthusiastic toward owners of used equipment.
