Nothing has gone wrong other than routine wear and tear to be expected in an older car. Some of the dash lights don't work anymore, and the air conditioning is temperamental, but works. It is a beautiful car to look at and to drive. Parts are expensive and the gas mileage is what you'd expect from a 2-ton car. Classic styling, it still looks great side by side with much newer cars. I'll keep it until it runs no more, that could be forever!
Looks like a family car, but is seriously fast.
I actually got lucky and got oil filters for a penny each!
