VBA Compile Syntax Error when trying to introduce variables

Hi All,
I am trying to derive a formula for excel.

Below works.

Dim Test As String
'Test = "Car; color=blue;"

But now I want to add more fields and I do not want them to be fixed. e.g. (Test = "Car; color=blue;Model =Toyota;Year=2002;")

so I change to

Dim Test As String
Dim X As String
Dim Y As String

X = Toyota
Y = 2002

Test = "Car; color=blue;Model ="X";Year="Y";"

But I faced synatx error. What could be the issue?

Any help is appreciated!

Thanks Joseph P for your help!

But what I got now was below when I do a mouse over:
Test = "Car; color=blue;Model ="X";Year="Y","

What I wanted was (Without hardcoding the values)
Test = "Car; color=blue;Model=Toyota;Year=2002,"

Here is the formula. Sorry, I am a beginner and am trying to pick things up.

Sub OPC()
Dim Test As String
Dim X As String
Dim Y As String

X = "Toyota"
Y = "2002"

Test = "Car; color=blue;Model =""X"";Year=""Y"";"
End Sub

Thanks JosephP! It works like a Charm! Issue marked as resolved!
