I'm not impressed by the phrase "the engine sounds good". If the guy from the car service who fixes my car had said that, I'd have believed him. But if this is coming from a guy trying to sell his old car, it sounds unconvincing. You'd write the complete characteristics of your car, listing them in a column. Then many users would be satisfied with your post. Take an example of a list of attributes from any car sales site like jdmbuysell.com. There they write them on a table, show some photos of documents for cars, etc.
