I doubt any investment is going to keep up with inflation in the foreseeable. I’m trying to see what I might need to buy in a year or two time with the idea of buying it at today’s prices. That includes paying to get work done.
That’s why I’ve persuaded my daughter that we should change her car now. She is still quite happy with the one that we bought new 6 years ago, but with second hand car prices being so high (great for trade ins) and my concern that an inflationary price increase could add a few grand to the manufacturers retail price, we have ordered a new one now. The ‘cost to change’ could be significantly more in a year or twos time (double whammy of second hand values falling and new car prices rising) and would wipe out the paltry interest that I will earn on the money many many times over.
