A pair of interesting threads and something which I have also needed to find an antidote for.
I have had many cars and bikes since I was 16, at the start because I could only afford to drive by buying a banger with some road tax on it then moving it on for a small profit when the tax ran out, also because by then, I was beginning to get bored with it. More recently ie 40 years ago, I got into Caterhams, because I wanted something more extreme for my fun motoring, and since then have built and owned 18 / 19 Sevens, mainly because of the aforementioned boredom, even with a Seven, and Caterham were always bring out a more powerful car which I lusted over, and by building them myself, I save a few thousand pounds, had a lot of fun and when I sold I made a small profit again - it also helps to justify another one to my good lady. Thew Seven thing has had to stop though, because at the age of 77 I find I have difficulty getting out - no upper body strength any longer.
I still find I am easily bored, even after 2 Morgan Three Wheelers, but I have retained interest in the current ARP4 since I bought it in 2016, although I am finding I don't drive it for fun very much, as others have commented. I recently sold a Golf R which I bought new and kept 6 years, now that was a car, but eventually boredom set in again, so it had to go. It has now been replaced with an Alpine A110 which I thought might be the car to recapture the 'driving for the sake of it' experience, but time has not allowed me to do that this year as we have put our house on the market and there is 30 years worth of stored cr*p to be moved, (no, not literal manure, but things that should have been disposed of, but seem to have been kept just in case there is a use for them).
Just a word of warning about the Alpine, because it cost of £40k when new, the government see fit to make us pay around £575 pa for the first 5 years, for the pleasure, nothing to do with emissions, but a wealth tax they snuck in at some stage. My ARP4 which cost £65k is only £225pa. Go figure!
