hey guys i have a line on a 90 wrangler soft top for around 1500$ with a rebuilt engine. this couple is moving back east and they cant take it with them. now i havent seen it yet but it is a soft top and a red body. i dont know if it has the 4.2 or the 4-banger but what is it that i should look out for. i am a suzuki/ford guy and know nothing about the ins and outs to look for in a used jeep please do tell!!
