2.slow is an interference engine. Since the timing belt is changed recently, should not be a problem for a while. Hopefully the new water pump has a metal impeller, the factory one was plastic. Window regulator clips are plastic and have a habit of breaking. Keep an eye on the rear calipers, it is quite common for them to seize due old age. Just use a good VW502 oil and OEM filters, good for 15000km oil change. 2.slow plus 5 speed is indestructible.
