In the past if you stuck something in a garage/barn for 40 years it would suddenly become rare and valuable, if it were actually worth something in the first place, it could then be worth quite a lot , and receive rose coloured praises from writers who actually never drove one in the first place. That said, I'm not sure how vehicles of today will fair in the future especially if say in another 40 years there's no such thing as petrol/diesel, or that if there is, it would be absolutely horrendous cost per litre. A while ago I bought a Ford Explorer and had it converted to LPG, it drove superbly was extremely reliable and did everything and more that a full size 4x4 could be expected to do. After 9 years and 80,000 the timing chain broke and ruined the engine (and people worry about timing belts). I could of rebuilt the engine, but at that age and mileage it really wasn't worth it, so it went to the great recycler in the sky, mainly because there were many 4x4 alternatives around, most giving as much performance and better economy that an old 'exploder'. However for me the point is that I'm unaware of any suitable replacement for my Stow n Go (as and when it gives up the ghost), hence I will keep mine going as long as is practicable. When it does die I'm not sure what its replacement will be, and I can't really think of any new or vintage which could even come close to it. What else can be used as a large comfortable car one minute, a van the next, and take a full load on a 600 mile trip at 80mph and still touch 30mpg ? 40 years ago you didn't worry much about car electrics as the bodywork was going to rust away long before that ever become a problem
