select m.MakeName as MakeName, m.ModelName as ModelName, c.VIN as VIN, c.StickerPrice as StickerPrice from (select MakeName, ModelID, ModelName from Make as ma inner join Model as mo on ma.MakeID = mo.ModelID) as m inner join Car as c on m.ModelID = c.ModelID

231,184 PointsYou're really close, but you're joining on dissimilar terms: "ma.MakeID = mo.ModelID
". Those should both be the same (MakeId).
Also, while this will work when fixed, you could simplify the query a good deal and still pass:
- you don't need a sub-query since JOINs can be chained
- you don't need any column aliases for the SELECT clause
- you don't need to qualify the columns with table aliases
