I recently had the opportunity to buy an absolutely gorgeous 1974 142s with a fresh-off-the-car-lot 200k miles for $1000. However, I ended up not going for it after talking to my local independent Volvo mechanic, because he said that the repair costs on the 140's were getting high and parts were hard to find. In particular he cited a local case where a customer was quoted $500 for a heater blower motor.
The 140 bug has struck me again, and after going to rockauto.com, I found that the parts really don't seem to be that expensive (the said blower motor costs $58.82, minus switch or resistor). Could some 140 owners please weigh in on this and tell me some of your experiences as far as availibility of parts and cost of repairs?

Thanks
