Yes, that is too much... Unless it is a fully loaded GTI in excellent condition with less than 35000 miles, that is Kelly Blue book value. A non turbo medium option/trimmed Golf with 100,000 miles in very good condition is only worth around $2,000.
You do not provide enough information for an accurate answer. What model Golf is it? How many miles on the odometer? Condition of the vehicle? Which engine, diesel or gasoline? All of these things effect the value. So click the link and see for yourself what it is worth.http://www.nadaguides.com/Cars/2001/Volkswagen/Golf
