Q&A

hello, I have a road trip coming up in a few weeks and I called my local auto repair guy and set an appointment but I'm just wondering about issues and price.
Main problems: Cruise Control is not working - the light won't come on nor will the buttons work. Speedometer is usually off by 5 miles (so if it says 35, you're really going 30 mph). My check engine light is constantly on. So it sounds like an average ABS problem I'm just wondering what the price will be.
additional problems:
gas pedal sticks when the car first starts - I've been told this is for defense but I doubt that. how much would it cost to fix this?
Basic Oil Change is needed.
Safety Check is needed apperantly (because it is over 155k miles)
I'm guesstimating that the cost of getting my car fixed will be close to $450?
I'm sure I'm off because I've heard ABS replacements can be $500 alone.
thank you so much for your help.
