A SAAB. No doubt. First of all people are scared of them. "Ooh, they aren't made anymore, you can't take them to the dealer because there is no dealer." True but only a putz takes a used car to a dealer. Dealers are notorious thieves.
"You can't get parts for them anymore" Sure you can. e-Europarts. Rock Auto, Autozone. No parts shortage. It's that "dealership mentality again" Dealerships love that.
Because people are stupid and believe the previous misconceptions, you can get a SAAB cheap. It has the quality of a Benz or BMW at a fraction of the price.
Safe? They are tanks with wheels. SAAB was all about safety. They made heavy cars with lots of steel. They made up for the weight by making powerful turbocharged 4 cylinder engines - really tough engines too, made for Swedish Iron, a particularly tough isotope of iron. Traction control, side airbags, stability control, winter drive mode and antilock brakes were standard.
Comfort. Few surpassed SAAB, with standard heated seats, leather upholstery and all kinds of other stuff that other car makers had as options. If you can get one of their TOTL models it will have ventilated memory seats. They even air conditioned the glove compartment.
A guy in Sweden put over a million miles on his SAAB. Reliable?
These were very expensive cars when they were new. Now it's a buyer's market because most people don't understand them.
