Merge duplicate records into 1 field

I have a database table that contains a list of contacts, some of those contacts might have multiple records, e.g.

CustomerID, CustomerName, Vehicle
1, Dan,

I'm pretty sure you can't do it via a single SQL query.

If it's a regular requirement, a Function should be made which is called for each customer ID.

SELECT   abc.CustomerID,
         dbo.udf_getCSVCustomerVehicles(abc.customerID)
FROM     (SELECT DISTINCT CustomerID
          FROM   TABLE) abc
ORDER BY abc.CustomerID

Then just create a scalar function which coalesces the values together into a variable and returns the result.
