I wonder a lot how I'll be able to keep the SVX running once parts start to run out and the electronic bits don't work any more. That's one of the reasons I don't drive mine much any more. I've gotten my money's worth out of the car, and it's still in excellent shape, so I don't mind leaving it in the garage and driving something else. Insurance doesn't cost me that much any more, either, so I don't feel like it's too much of a waste.
Occasionally I do, though. Then I get to drive it and it all makes sense.
Keeping the SVX and picking up a beater has definitely set me back on the car scale. Some of my friends drive BMWs and I drive an oil-burning 20-year old Toyota.
At least it's a relatively cool Toyota.
Anyway, that's my advice. If you want to keep the car, put it away before the expensive stuff starts to break. If you want to drive it every day, go ahead - but don't expect it to be 100% reliable and Corolla-cheap to maintain. You're going to have to spend to keep it running well and to avoid the expensive surprises.
