92 sc three

I'm looking into buying either a 90-93 LS 400 or a 92-95 ES 300 (both would be under 100k miles) as a daily driver. Obviously they are clearly two different types of cars with different kinds of problems. From a practical standpoint, which would be the most trouble free and require the least amount of $$$ to keep it running? Any help / suggestions would be greatly appreciated.

Thanks in advance.
