You need to remove the comma(,) before FROM:
OleDbCommand OleDbCmd = new OleDbCommand(("SELECT FirstName, LastName, Salutation, PurchaseDate, ContractEndDate, Make, Model, RegistrationNumber, DateOfRegistration, OTRPrice, CashDeposit, PXPrice, BalanceToFinance, SalesConsultant, FullAddress, HomeTel, WorkTel, MobileTel, email, NewOrUsed, FinanceType, MonthlyPayment, GFVorBalloon, TermInMonths, APR, ContractNumber, " + (Profile.Company) + " AS Company ID FROM " + sWorkbook), OleDbConn);
Good luck!
