well ive not had one problem with either of my supra's apart from the obvious things such as tyres and stuff these cars are well known for their excellent reliablility so i wouldnt worry to much about parts needing replacing, their are a few common issues but most are not expensive to fix such as the boot rubbers which degrade over time and it results in an anoying rattling but this is a cheap fix so no worries!, both cars can be a bit of a handful in inexperienced hands of rwd cars, expect a few times when the back end will go especially on roundabouts! but for me thats the fun of a rwd drive car!
