I have an offer to buy a 1987 780 bertone black w/ dark gray leather.

The car has been owned by a relatively well off person who loves cars (merc bmw volvo) and pampers them at specialized mechanics.

Don't know miles. Looks "good" in the picture. I suspect the cosmetic condition of the vehicle to be nice but not in any rare super shape.

His wife told me the engine has a "hole" in it. i.e. engine needs repair.
It is not being driven. They were quoted between 1K and 2K to replace with rebuilt. Anyhow manybe a head gasket. She said it ran very well for years beforehand and was serviced at a volvo specialist.

Questions:
1.. What's the motor in this car?
2.. Did they have biodegradable wiring problems?
3.. Are they known for any severe problems?

I would have to swap for a current car. Would I be crazy to sell off my really nice pampered 240 and buy this as the next project and daily work driver?

I can probably get it for 600$.

Let me know your thoughts, let's not be impulsive, I have three kids and a wife who gets upset when I am in the garage playing with my cars.

Let me know.
