Having owned classic Triumphs for over 35 years, I see it all too often - someone has some spare cash and decides to buy a classic car. Having decided on make /model, they get one, but within 12 months or so the car is up for sale. Why? Having driven modern vehicles, the reality of driving a classic car doesn't quite seem as appealing once they've bought the car, with unseen corrosion showing, the frequent maintenance required and the general lack of 'mod cons'. Whilst they may remember driving cars in the 60's / 70's, the harsh reality is that cars have moved on leaps and bounds, and unless you class yourself as a fanatic of the make /model you buy, you may find that after the initial excitement of owning a classic car, the reality of ownership isn't quite as appealing and a bit of a culture shock when you go back to a classic car.
It's a bit like the person who decides to buy a sports car for weekends. Invariably, they end up for sale within a year or so, as the owner didn't use them enough or the car they bought wasn't as practical as they first thought.
The other point which should go without saying is to fully research the problem areas of the car you would like to buy; as with OOF, there is a plenty of information on the forums about what to look for, and take someone with you when you go to look. It's easy to see your 'dream' car through rose tinted glasses, and the friend with you may just pull back on the reins and prevent you buying a 'pup'. And don't buy the first one you see, unless it is the perfect car (which many turn out not to be).
And if you are not particularly handy with the spanners, who is going to maintain it for you? Finding someone familiar with your particular car who knows them sufficiently to lavish the care they may need, may not be on your doorstep (a bit like the Omega!).
Just be mindful of the availability of spares - who would have thought for instance that a Ford Granada from the 80's with a few corrosion issues would be a problem? The actual problem is that many of the panels are virtually unobtainable, and if found, cost a small fortune. Would you pay £135 for a washer bottle (no pump in that)? I was recently taking to a Ford Escort owner who had to pay that figure because of their rarity.
So it's worth doing your homework.....
Just a few thoughts for what it's worth.
