I'm looking into buying a mt2400 or vantage. I don't need a up to date tool since the newest car this could be on would be a 1999. It'll be mostly used on a 1990 Jeep wrangler. Its running but there's some questionable things that a mt2500 isn't going to cover. so my question is what would I need for it, what is it capable of, features etc. any info would be great !
