The key things to watch for are rust and frame damage, also a very high mileage car will not hold up the the added weight and power of an LS swap as well as a low mileage car.
Shipping has gotten incredibly expensive, I bought a solid running local car for less than a salvage wreck plus shipping.
That said, I have a green 5 speed, sunroof, 120k miles, zero rust, zero frame damage, newer clutch and shocks, etc...car I will be selling as soon as I finish swapping int the black interior from my other ti, I bought it to get the gray interior I wanted.
This is the kind of car you want to buy for the long term, not a worn out, rusted, damaged car, it will be far less costly and a far less headache over time, not much time at that either.
It as some parts store shocks on it but I have a set of Bilstien shocks and springs(one shock is blown) I could put on it for a moderate cost as well.
If I was going to stay in my home and keep my shop, I have a loaded shop with a lift, metal fab tools, tubing bender........I would do an LS swap into it as I have a forged LS1 sitting here. I am selling out nearly everything I have and going full time RV with the CE edition 300HP S52 in the back of the trailer though.
Good day
