The Sebring features an inline 6 cylinder engine with Lucas direct fuel injection. The engine came in 3 sizes during the car's lifespan, with later models getting the bigger engines. The engine was paired with a ZF 5 speed manual or a 3 speed Borg Warner automatic transmission. This would be the first Italian car to have an automatic transmission, which was quickly becoming the standard in places like the United States. All of these cars were rear wheel drive.
The Series 1 Sebring could do 0 - 60mph in 8.5 seconds, not an impressive number today but decent during its time. Later models would get the engine upgrades that would eventually boost horsepower to 255 in the final Tipo 101.A10 series.
Maserati was hit by financial troubles at the end of the 1960's, and they had to cut back on some of their older models. The Sebring hit the chopping block in 1969.
The Sebring was sold as a 2+2 coupe or a 2 seat spyder convertible. The convertible is more desireable by collectors. With productions numbers so low, your chances of finding one of these cars is slim. I suggest you look on places like eBay, where one might pop up once every few months or so.
