My 92 300E has 112k miles on it. I've been the second owner for the last nine years. Thanks to the IDIOTS in DC I'll be keeping it for a few more years. With the exception of the water pump hose all remaining hoses are original.
Question: As a precautionary measure before taking a trip this spring/summer which hoses should I consider replacing? They appear good from the outside but usually they deteriorate from the inside out.
