Changing my -96 Lumina to -96 Lumina LS?

[Nipa]

I bought few moths ago a -96 Lumina with "only" 100k miles. Now I found out, that it was crashed in -96 (in Finland, there is no such thing written in title). It was fixed propely, but the "frame" was left open behind the wheelwell (don't know better way to explain it) and it has started to rust! A friend of mine said, that it will last only 2-3 years!! Now the seller agreed to change the car to another one (there is no really laws that would cover used car market that much ), which has app. 155k miles. It is quite good condition (seen only in pictures) but should I even consider to trade it? Is 155k miles too much (ofcourse depending on service)?

Another quick question; what are the actual differences between Lumina --> Lumina LS? Thanks

Not sure about whether or not you should swap vehicles. However, there aren't a lot of diffferences between a stock lumina and an LS. The second generation lumina (1995-up) came in 3 trim levels: Base, LS, and LTZ. The base and LS came with a 3.1L V6 engine while the LTZ had either the 3.1 or the 3.8L. The LS came with a few more options (than the base model), such as: leather, sunroof, bucket seats w/ floor console, dual exhaust, dual zone climate control, alloy wheels, tape or CD player, optional guage cluster (including a tach), and keyless entry. That's really about it. Essentially with the LS you get a few more perks. However, they seem to vary from LS to LS....that is, not every LS has all of these options. Like I stated, the main difference between the trim levels was that the LTZ had the optional 3.8L engine which became standard equipment in '98 or '99 (I can't remember which year it was).
