I bought my Volvo S70 in 2000 with 24,000 miles on it, but sadly had to say goodbye to it this week.
While it didn't get me to 300K, it did get me to 286,000.
The only work I ever had done was sparks plugs & wires, fuel filter, radiator hoses and alternator.
The car was rock solid and reliable.
I was so impressed with the car, I bought another S70 - hopefully this one gets me over 200K also.
