Hi Everyone! So I am planning a road trip down I-5 from Seattle to San Diego, CA and back up highway 101. I am taking the 1992 Audi 100 S and am looking for any advice and suggestions that may help. My car has 140k on it and I believe in the Audi and that it can make it the whole way...but I would love any input on ideas of how to make this trip the easiest on the Audi.
Thanks in advance.

Just check your fluids every time you put gas in your car. I have a 92 s (131k)and I just put close to 2k miles in six days driving down to Florida. I can say that this is one of the best cars that I've ever traveled with.
Have a good trip!
