Very subjective question....
If you tend to keep your vehicles till the bitter end, then the miles is a non-issue. In fact, you can save $$$ by opting for the lift when its time to replace springs/shocks/balljoints/etc anyway.
If you rely on owning a vehicle in that 'sweet spot' of reliability with low cost maintenance... and replacing it while it still has good resale value, then maybe not.
