At the ripe old age of 65 and having been involved with auto repairs and sales most all of those years I must say that the 2002' Saturn Vue 4 cylinder 5-speed manual is a great bargain. I have owned too many vehicles to count. At 120k miles it uses no oil and in the last 20k that we have owned it, 1-exhaust hanger is the only repair. It has had full synthetic oil since it was born. 5-speed shifter is a bit notchy but adequate.
Gas mileage 22 city and 28 highway. Reliable. All seats fold down including the front passengers so I can load 8ft 2x4's and close the hatch! 4-cylinder engine with a real timing chain-not a belt.
Keep this engine but refine it and keep the 5-speed manual and also refine it and make it smoother shifting.
