93 SC400 guy

So my 93 sc400 has 230,000 in it. Just replaced rack n pinion, right rear wheel hub n bearing, and transmission currently. Upgraded band in tranny to high performance, wider one, replaced u joints and some drive train the tranny connects to....2k for r&p, and $2500 for tranny n ujoints, drive train thingy....should I get a tune up on this car after tranny comes back working or will they tune it for me when they put it back together? Love my car. Next is seat leather or good covers and instrument panels with working displays on them. Plus driver door handle is broken, so rekey all of them probably too. Basic maintenance is a must and can stack up quick. Not to mention my driver door inner trim panel fell off....lol. it's a test of my patience and wallet I am thinking. But I keep on rolling......
