I tryed switching baterries from my 94 sc300 to my 93 sc300 but the same thing happened the next morning, but it didnt happen in the 94. As for your thing about having the same cars...they arent the same...i only have 3 sport coupes and one is a 93 300 the other is a 94 300 and the other is a 92 400...the other lex i have is a 93 LS400(wifes car). As for buying an 8 series car...i already have one coming in sometime in the first week of january...as for giving up a lexus for it...YEA RIGHT!...im selling the old accord(my sons car) to get my self an 850I 6 speed and my son is getting my 93 sc300 if i can fix this problem.
