went on volvo's owner site and checked on the curb weights and it's around 3200 lbs for curb weight for 1998 as well as 2001. you might wanna get a later year c70 HPT, i remember the c70 had been delayed quite a bit because of structural problems, most likely with the convertible, but in any case...might wanna look for later years. also, as a side note cause u'r looking for manual, later years provided c70 hpt with optional 5 speed automatics, compared to early years where it was only optional 4 speed automatic. all years had 20 mm front and rear sway bars.
