I used two queries:
Query1:
SELECT tbl_purchases.VehicleID, Min(tbl_purchases.PurchaseDate) AS
MinOfPurchaseDate
FROM tbl_purchases
GROUP BY tbl_purchases.VehicleID;
Query2:
SELECT Query1.VehicleID, tbl_purchases.PurchaseID,
Query1.MinOfPurchaseDate, tbl_purchases.Comment
FROM Query1 INNER JOIN tbl_purchases ON (Query1.VehicleID =
tbl_purchases.VehicleID) AND (Query1.MinOfPurchaseDate =
tbl_purchases.PurchaseDate)
GROUP BY Query1.VehicleID, tbl_purchases.PurchaseID,
Query1.MinOfPurchaseDate, tbl_purchases.Comment;
Cheers,
