although i haven't driven a manual JZZ30 i would any day of the week take the soarer over the A70 supra
It is just a nice refined car, minimal cabin noise but still reasonably powerful.
th z30 does feel heavy though admittedly and this is evident just looking at an open door on them (most complex door hinge i have seen in a while), they are bloody long and wide too so if you are afraid of parking in shopping centre car parks or city parking, this may become a big issue
the supra is fun and the chairs do hug you more but my persoanl preference for every day living with a car is the z30 soarer hands down.
note this was with an automatic soarer though.
