Qrylifecyclemodels
SELECT QryDateDifModels.[MODEL RANGE], QryDateDifModels.Expr1 AS [Life Cycle], Count(QryDateDifModels.Expr1) AS [Total vehicles]
FROM QryDateDifModels
GROUP BY QryDateDifModels.[MODEL RANGE], QryDateDifModels.Expr1;


SELECT QryLifeCycleModels.[Life Cycle] AS [Life Cycle], QryLifeCycleModels.[Total vehicles] AS [Maximum Total Vehicles], QryLifeCycleModels.[model range]
FROM QryLifeCycleModels
WHERE (((QryLifeCycleModels.[Total vehicles])=(select max([Total vehicles]) from QryLifeCycleModels)));

SELECT t.[Life Cycle] AS [Life Cycle], t.[Total vehicles] AS [Maximum Total Vehicles], t.[model range]
FROM QryLifeCycleModels t
WHERE (((t.[Total vehicles])=(select max(i.[Total vehicles]) from QryLifeCycleModels i where i.[model range] = t.[model range] )));
