This is by far the most costly car anyone could buy. Volvos are the third most expensive brand of car to own and I got to experience the brunt of that with this. I put $5k of repairs into it, drove it slowly, braked lightly, and never went fast, used the expensive gas, and nice oil yet this car would still break down easily every 2.5k miles and every repair would be about $1k. Its not a fast car. It doesn't handle well. It doesn't get good mpg. There is no reason to own a Volvo. I am glad to say I upgraded to a 1988 Camry that has better acceleration and is cheap to own and is reliable.
I enjoy this car, purchased it with 142k miles 2years ago. Had a no start, no charge problem last summer, replaced battery with used $30 battery, good as new. Happened again this year, this time alternator gave out, replaced both battery and alternator for $400. I did the labor myself and saved about $400. I only put castrol edge full synthetic oil, usually on sale for $40 for 5 quarts and filter. Car take 7.29 liters, you do the math. Update 8-10-2016: Recently had CEL read evap system and cylinder 5 misfire. Then loss of power and performance when warmed up. Changed spark plugs and ignition coil, no change. Cleaned out ETM then it ran like a champ for a while. CEL and engine service system urgent came out again. I might need a new ETM or rebuild now. Bought code reader but shows no codes, magically disappeared. Might be time to find a newer one with a 2.5 or 4.4.
I really wanted to like this car. It was so comfertable and I felt very safe all of the time. Drove like a dream. However it has been a constant money pit The car has 163,000 miles on it so it is old but its not going to last with out hundreds maybe thousands of dollars invested. Its been constant for the last two years: In addition routine work I have also had to replace struts, fix the fuel pump, the coils, the head light got busted and the electics have never been the same, the ac is shot, the power locks are shot, had to have the power steering fixed, and ALL of the fabric lining is coming off. Lots of money, time, and towing
