You really need to find a pick&pull for a 'new' MAF sensor. The ABS module can be 'repaired' for around $100. Check Google for an outfit close to you.

With those two items repaired, you can ask for more money.

In its present state, assuming all of the litter is cleaned out of the car, including the trunk and glove box/door pockets, and the car is freshly washed and waxed, I would start higher than your asking price and see what happens.

Remember, used car prices have gone up lately. Check Craigslist in your area and search for Volvo S70 and see what others are selling theirs for. You have 'low' mileage and probably maintenance history.

Regarding maint history, most shops carry computerized records which they can print off for you. The list contains what was done and when it was done, no prices or names.
