My "Sven-Göran", a 240 GL sedan, was born at the Torslanda plant in spring 1987, the year my father bought it. He drove it for 123,000 km (76,000 miles) through the years until the spring of 2002, by the time it was replaced by a Peugeot 307. At which point Sven-Göran moved in with us.
There is nothing really special about Sven-Göran. Except.... The initiated few will appreciate the fact that this car looks almost like it did when brand new. Outside. Inside. Underside. Engine compartment. My father has put a lot of effort into upkeeping over the years, including a full anti-rust treatment every four years. Always garaged when not in use. No scratches, chipped paint, dents or faded interior.
There are mainly two reasons for this: First and most important - my father being the perfectionist that he is and always has been. Second - the price paid in '87 says a lot. As cars in my country is regarded by the government as a heavily punishable luxury, car taxation is taken to the utmost extreme. So having done the offense of getting a car, you'd better make it last as long as possible. In the seventies/eighties/early nineties there were few better starting points than a Volvo 240. Still isn't, come to think of it.

Well, if one can give reasons for love, here are a few:
You and your loved ones are surrounded by lots of Swedish steel.
Fellow Brickboarder Marc kindly sent me this bit of interesting information:
"The
Insurance Institute of Highway Safety (www.IIHS.org)
did a 5 year study of death rates by model by series, of all model years
from 1988 to 1992. According to the IIHS "Status Report" magazine
cover article, Vol. 29, No. 11, October 8, 1994: "The 240 didn't
record a single driver death during the five years of the study."
Interestingly, it was the ONLY vehicle that had no driver deaths."
Engine, transmission and drivetrain are next to indestructible.
I would not call the 240 exceptionally reliable though, I find durable being a better word.
A very conventional design with few quirks. Someone has called it "the world's most modern veteran car".
Keep in mind that the 240 was built over a period of 18 years (1975-93), and second-hand and aftermarket parts are normally cheap and easy to find. Here in Scandinavia where the 240 was a top selling car you will find 240 parts "behind every bush". Go for a walk in the woods, and you shall find.
The body is prone to leaking, particularly in the windshield/firewall area. Water may hide under the carpets. And seep into the sills. And create all sorts of disasters as it passes the fuse box. If you find a rust-free one, do everything you possibly can to keep it that way.
For the n/a motors, focus was on longevity rather than on maximum power. If you long for the smell of burnt rubber, get a GTI or something. Or what would have been my choice - a 240 turbo intercooler.
If you don't mind reading my personal reasons for having/loving/coddling this particular 240 here is a long-winded rant, consider yourself warned.
