The first generation Volvo C70 was sold from 1997 until 2005. It was sold with a choice of two I5 engines, the low pressure option and the high pressure option. Both engines were turbocharged - part of Volvo's new sporty philosophy. It was based on the 850 luxury sedan, but the engineering was done by Tom Walkinshaw Racing. The first generation model would make it to U.S. shores for the first time in 1998.
Although the Volvo C70 did not sell well in the United States at first, it was well-liked by Volvo enthusiasts, as it brought the brand into the modern age.
The second generation C70, sold since 2006, only comes in one body type: the coupe convertible. It features a 3 part retractable metal roof that can be folded at the press of a button into the trunk of the car in less than 30 seconds.
The new C70 has a fresh design that is very different from the first generation models. Despite its sporty performance, it remains a very safe car, just like any other Volvo. It is among the safest convertibles on the market and a perennial Top Safety Pick from the Insurance Institute for Highway Safety.
The first generation C70 cars are available in decent numbers on the used car market. The more recent models might be a little rare, but there are some places where you can find them in decent numbers. EBay is one place I look to find good deals on newer used cars. I'm sure you can find both first and second generation models listed on there right now.
